Introduction

Hellhole Canyon and Culp Valley are a natural floral unit, since the upper part of Hellhole Canyon is most-easily accessed via Culp Valley. The main access road to Borrego Springs in this area travels through Culp Valley and ends at the bottom of Hellhole Canyon. One of the main hiking trails in this area, the California Riding and Hiking Trail, goes from Culp Valley to the bottom of Hellhole Canyon.

Culp Valley is the first part of Anza-Borrego Desert State Park encountered by visitors traveling along S22 from Ranchita and the Montezuma Valley. You enter Anza-Borrego Desert State Park just before the road crests at the lip of the Salton Sea erosional basin and you travel down the Montezuma Grade. This is a very dramatic way to enter the park, with terrain so challenging that no road was built until S22 was finished in 1964 after ten years of construction.

The first five miles of S22 past the crest, from mile marker 6.5 to 11.6 on S22, is in Culp Valley. There is a popular campground, the Culp Valley Primitive Campground, at a turnoff near mile marker 9.2 on S22. After mile marker 11.6, the road descends into Culp Canyon, and then heads northeast along the east side of the ridge separating Hellhole Canyon from the southern part of Borrego Valley.

Immediately before the final sweeping curve to the right on S22, just before S22 meets Palm Canyon Road (turnoff to Visitor Center) at the base of Hellhole Canyon on the western outskirts of Borrego Springs, there is a large parking lot, with two restrooms, on the left (west side of S22). (See map here.) This is the parking lot for the Hellhole Canyon Trail, and for Little Surprise Canyon, as well as another access point for the California Hiking and Riding Trail.

Hellhole Canyon is one of the more popular areas of Anza-Borrego Desert State Park. The five mile roundtrip hike to Maidenhair Falls and the Hellhole Palms, with flowing water most of the year, is the top attraction. The Visitor Center often directs non-hikers to Little Surprise Canyon, right next to the Hellhole Canyon parking area, for a good wildflower show in the spring that can be enjoyed with very little walking.

The lower part of the California Hiking and Riding Trail crosses the base of the Hellhole Canyon alluvial fan, beginning at the southeast corner of the Visitor Center parking lot and crossing the Hellhole Canyon Trail, and traveling up the south wall of Hellhole Canyon to Culp Valley.

This checklist is only a start at the flora of this Canyon, since many of the entries come from vouchers I haven't yet reviewed, and I haven't yet vouchered all of the new records I have found so that my determinations can be reviewed. This checklist can only be considered a decent flora after I finish both of those tasks. This checklist will be revised as I work on both of those tasks.

Location

Hellhole Canyon is west of Borrego Springs; Culp Valley is a flattish valley above the south wall of Hellhole Canyon:

The boundaries of this Flora are shown in more detail in the map below:

The Culp Valley Floral Area includes Culp Valley itself, plus the following areas:

• the area to the west extending up to the lip of its erosional basin at the east edge of Montezuma Valley at ~4600 feet elevation (Ranchita is in the Montezuma Valley).

• the area to the south up to Pinyon Ridge, reaching a peak elevation of 4573 feet at Wilson Peak. The Floral Area boundary is drawn a bit south of the ridgeline, since Pinyon Ridge is accessed by a Jeep Trail from Culp Valley.

• the area to the east down to the 3000 foot elevation contour.

• the area to the north down to the 3000 foot elevation contour, including most of the South Fork of the Hellhole River, accessed by a Jeep Trail from Culp Valley.

Culp Valley itself extends down to 2800 feet elevation, where Culp Canyon begins.

The total elevation range for the Culp Valley Floral Area is 2800 - 4600 feet.

The Hellhole Canyon Flora Area follows the drainage basin of Hellhole Canyon up to an elevation of 3000 feet, extending to the ridge containing Panorama Outlook on the north, the 3000 foot contour in the west and southwest, and following the top of the ridge extending from Culp Valley to Borrego Springs on the southeast. The latter ridge divides the drainage to Hellhole Canyon and the drainage to the portion of the Borrego Valley that is south of Christmas Circle in Borrego Springs.

The total elevation range for the Hellhole Canyon Area is 835 feet at the Visitor Center to 3000 feet.

The following map shows the areas surveyed so far that are included in the checklist below:

Note that very little of Culp Valley has been surveyed so far, being only covered by most of the top part of the California Riding and Hiking Trail.

The checklist below contains separate entries for the species found in each of these areas:

• Little Surprise Canyon, surveyed along the maze of routes shown in the map above. Its flora is also given separately.

• Hellhole Canyon Trail, to a bit beyond Maidenhair Falls and the Hellhole Palms. See also its detailed plant trail guide.

• The California Riding and Hiking Trail, from the Visitor Center to its intersection with the trail from the Culp Valley Primitive Camp, along with the road to S22 from that intersection. Separate entries are given in the checklist below for the top portion of this route, above a saddle at an elevation of 2580 feet, and for the bottom portion. Note that this dividing saddle is not exactly at the boundary between the two floral areas, but it is close.

  See also the detailed plant trail guides for the top part and bottom part. Note that these guides are to the entire trail, one for each direction, but the checklist below uses only the part of each guide above and below the 2580 foot saddle. The saddle is at mile 2.38 on the way down, and mile 3.10 on the way up.

Procedure For Compiling The Checklist

The Checklist was compiled from field work done by myself and coworkers, and from online vouchers.

Field Work

The checklist from our field work was compiled using the results up to and including 15 January 2010, which consisted of a total of 17 different full days of field work with a total of 40 people-days. The largest number of trips were done by the following people:

# field days	Person
17	Tom Chester
5	Kay Madore
3	Mike Crouse
2	Wayne Armstrong and Paula Knoll

People devoting one day to a survey were: James Dillane, Michael Charters, RT Hawke, Shaun Hawke, Aaron Schusteff, Kate Shapiro, Pam Pallette, Vince Balch, Preston Taylor, and Richard Sapiro.

The surveys were all done in the non-prime time of December and January, except for one survey of Hellhole Canyon on 25 March 2005 and one survey of Little Surprise Canyon on 1 April 2008. See the links immediately above for detailed information about the area covered, the dates of coverage, and the participants, for each of the surveyed sections.

The following table gives the number of species found in each area, the total number and the total number fairly confidently identified, along with elevation ranges and miles covered in each survey area, in order of descending elevation of the survey:

Survey	# miles	Elevation (feet)		# Taxa	# Identified Taxa
		Min	Max
California Riding and Hiking Trail Top Part	2.38	2580	3520	93	84
California Riding and Hiking Trail Bottom Part	3.10	835	2580	111	106
Hellhole Canyon Trail	2.65	880	2040	187	182
Little Surprise Canyon	~2.25	880	1080	97	96

Because most of the trips were done in December and January, some of the species found could not be fully identified, although they could be distinguished in the field. These species were usually dead plants from the previous year, but sometimes were babies of the current year. Examples are species in the following genera: Datura, Nemacladus, Cryptantha, Lupinus. Observations of those species are not present in the checklist below, which contains only the fairly-confidently-identified taxa. Hence those surveys should not be considered as complete records of all the species in the area surveyed.

Most of these taxa are almost certainly identified correctly, but a small percentage of the fairly-confidently-identified taxa are what I call 95% confidence taxa. These are ones that are highly likely to be the determined taxa, but did not have flowers or fruit to make the determination 100%. One would expect that up to 5% of such species might turn out to be incorrectly identified.

One taxon, the Lycium species in Hellhole Canyon, could not be determined any further in the field, since there were no flowers on any of the plants. It was placed as L. andersonii in the checklist below, solely since that is the only Lycium species vouchered or observed in this area. That placement may of course be incorrect.

Altogether, 246 separate taxa were found in these surveys.

Vouchers

The vouchers were obtained from searches of the Consortium of California Herbaria on 19 January 2010.

The Consortium database was searched for the subset of vouchers with coordinates using a rectangle with corners of (33.264,-116.456) and (33.231, -116.406) for Hellhole Canyon, and another rectangle with corners of (33.234, -116.504) and (33.174, -116.433) for Culp Valley. In addition, the database was searched for all vouchers, with and without coordinates, containing one of the following words in the locality field: Hellhole, Hell hole, Flatcat, Flat cat, and Culp. Searches were also made using the name of springs in Culp Valley, but no additional vouchers were retrieved.

In addition, a separate search was made for every taxon found in the field surveys that had no vouchers found in either area. This did not result in any additional vouchers for this area, making it likely that the previous searches were highly complete.

Duplicate vouchers were then eliminated. The locality field in each remaining voucher was then manually reviewed, and the vouchers were placed in the Culp Valley Floral Area, the Hellhole Canyon Floral Area, or were discarded if they were from another area. Vouchers from Culp Canyon were discarded, since they are outside the Culp Valley Area defined here.

Two vouchers of Chinese privet, Ligustrum sinense, were removed from further consideration, since they were found only near an old homestead in Culp Valley and this species is not otherwise known to be reproducing in the wild in southern California.

The determination on one voucher of Quercus john-tuckeri was treated as a voucher of Q. cornelius-mulleri, since that is a highly-likely misdetermination.

A total of 369 vouchers were found, 85 from the Hellhole Canyon Area and 284 from the Culp Valley area.

Altogether, 202 separate taxa were found in these vouchers, 60 from Hellhole Canyon and 167 from Culp Valley.

The top collectors for Hellhole Canyon were:

# Vouchers	% Vouchers	Collector(s)

Important Caveats

Please note the following important caveats about this preliminary Checklist:

• I have not looked at any of the vouchers yet, so I cannot vouch for their determinations. I have checked only the names of the taxa to make sure it was not unreasonable for them to occur here.

• Some taxa present in the checklist only from our observations have not been 100% identified yet, since they were never observed in bloom.

• Several of the surveyed areas are incomplete for annuals and perennials, since they have not yet been covered at prime time.

• This checklist is very incomplete for Culp Valley, since no dedicated survey has ever been done there in prime time. (Our single survey trail there was covered only in January so far.) Most of the entries come from widely-scattered vouchers, and most of the area of Culp Valley has not been botanized. (See the numbers below.)

• The checklist is somewhat incomplete for Hellhole Canyon, since most of the Canyon has not been covered by surveys in prime time. However, this checklist is a good start toward its flora, since several areas there have been covered in prime time.

• This is a very preliminary first draft Checklist, compiled quickly and without review by other knowledgeable botanists, and so well may contain bonehead errors.

Checklist for Culp Valley / Hellhole Canyon

This checklist contains 328 taxa, with 204 recorded in the Culp Valley area and 238 recorded in the Hellhole Canyon area.

The composition of the checklist is very different in the two areas. Since three of our surveys were done in the Hellhole Canyon area, and very few vouchers have been collected from there, the vast majority of the Hellhole Canyon portion of the checklist comes from our surveys. Of the 238 Hellhole Canyon Taxa, 232 were from our surveys and 60 were from vouchers.

In contrast, only one of our surveys was done in the Culp Valley area, and it was done only in January. It therefore is missing a lot of the annual and perennial species. Of the 204 Culp Valley taxa, 84 were from our surveys and 167 were from vouchers. As mentioned above, a lot of Culp Valley has not yet been botanized, so this checklist is very incomplete for Culp Valley.

One of the entries in the checklist, Descurainia pinnata, is not distinct from the two subspecies also given in the checklist. It has been given separately to indicate that this species was recorded in one of the surveys, but could not be determined to subspecies since the plants were dead.

Notes on some species in the checklist:

• The most common cholla by far in Culp Valley and Hellhole Canyon is Opuntia ganderi. O. parryi lives almost entirely to the west of Montezuma Valley. The voucher of O. parryi was found at 4140 feet elevation at the intersection of the Jasper Trail and Old Culp Valley Road. It is not unexpected that there would be some interlopers of O. parryi at the higher elevations in this Floral Area.

• The Opuntia vaseyi in the checklist is the same as everyone else's O. phaeacantha. I have yet to see anywhere in southern California a single prickly pear with the white style and white filaments used to key out O. phaeacantha in the Jepson Manual. The flowers of the specimens here are indistinguishable in that respect from the flowers of O. vaseyi on the coastal side of the mountains.

I make the working list available online for two reasons. First, I know others will appreciate having such a list, even if it is preliminary. Second, I hope I will get feedback from others who find errors or omissions in this list.

The Checklist is sorted first by category - ferns, dicots, and monocots - and then by family and scientific name. The Family and Scientific Name are from the Jepson Manual, with the Family being given by the first three letters. See Plant Family Abbreviations to decode the abbreviations. An asterisk before the Common Name indicates a non-native taxon.

There are four columns that follow the name for each taxa, one for each of the surveyed areas. Each column gives a rough estimate of the number of plants, and the number of locations for each species, in each surveyed area (#Plants / #Locations). Maximum values are 99 plants, and 9 locations. The main intent of this column is to indicate the species for which very few plants or locations were found. These are not just values that correspond to plants within touching distance of the trail, as given in my plant trail guides; these include plants seen in the area around each trail, as given in my floras.

The next two columns give the number of vouchers (# Vouchers) found in the Hellhole Canyon Area and the Culp Valley Area.

The surveyed areas are all in the Hellhole Canyon Floral Area except for the top portion of the California Riding and Hiking Trail (CA R&H), which is mostly, but not entirely, in the Culp Valley Floral Area.

The presentation of the surveyed areas in the table from left to right is in declining order of maximum elevation: 3520-2580; 2580-835; 2040-880; 1080-880 feet for CA R&H top; CA R&H bottom; Hellhole; and Little Surprise, respectively.

The elevation range for the Culp Valley Floral Area is 2800-4600 feet. The elevation range for the Hellhole Canyon Area is 835-3000 feet.

This is a working list, about which I make no guarantees at all until I officially release it. Use at your own risk!
