Introduction This trail guide begins at the Penny Pines parking area on Sunrise Highway (S1) at mile 27.3. There is parking on both sides of the road. The only signage is Penny Pines, and there are no restrooms at or near the trailhead. Note that this trip does not begin at the signed Garnet Peak Trail near mile 27.8, which is a shorter, more direct way to get to Garnet Peak.
At the Penny Pines parking area, the guide begins at the Penny Pines entrance on the left (north), not the blocked-off shortcut entrance on the right. The trail curves right 90° twice to join the PCT at mile 0.11, and the guide follows the PCT to a junction with the Garnet Peak Trail. It then takes the Garnet Peak Trail to the top of Garnet Peak.
See also Flora of the Penny Pines to Garnet Peak Area in Family Order, which contains links for every species to the Jepson Manual treatment and to Calphotos.
The entire area of the trail beginning at mile 0.38 burned in 2002 (Pines Fire) and again in 2013 (Chariot Fire). The area up to mile 0.38 burned in 2003 (Cedar Fire) and again in 2013 (Chariot Fire).
The Introduction and Plant Trail Guide have been updated from the 9/29/16 fieldwork, but nothing else on this page has been updated since 2005.

Number of Unique Taxa On This Trail
This histogram has not been updated from the 7/2/04 fieldwork.
The following histogram gives the number of trails in our database that contain each taxon on this trail. There were 75 trails in our database when this histogram was made; 2 of those trails, including this one, are in this section of the Laguna Mountains. A number of "1" means the taxon has only been found on this trail among the trails in our database; numbers of "2" or smaller may indicate taxa found only at in this area of the Laguna Mountains.

The unidentified ones are marked with ? or sp in the id? column in the guide, and do not have any number given in the #all column.
Note how different the Laguna flora is from the rest of Southern California! 14 taxa do not appear on any other trail in our database, and many of the 13 taxa that appear on only two trails also appear on another Laguna Mountain trail.
Fieldwork Dates and Summary of List Changes With Time The following table gives the dates the trail was walked and taxa recorded. After each visit, the table gives the total number of taxa on the list and the breakdown of the taxa without positive identification. See Explanation of Plant Trail Guides to understand the symbols below.
Visit Date Visit # # taxa # "?" # "sp" # "~" # "ssp" 5/10/2003 1 36 1 5 1 1 3/13/2004 2 85 13 11 16 3 6/15/2004 3 137 7 9 19 8 6/21/2004 4 137 7 9 17 8 The 5/10/03 fieldwork was only to mile 0.95, and done "on the side" during a fairly-fast-paced hike with a Botany Class. We thank Michelle Balk and Megan S. Enright for assistance with the 5/10/03 fieldwork.
The 3/13/04 fieldwork was after the entire trail had burned in either 2002 or 2003. No attempt was made to try to record all the different baby annuals, and since many shrubs and perennials were completely burned, no attempt was made to try to divine their identity.
On 6/15/04, we did for the first time try to identify all species we saw.
The fieldwork on 6/21/04 was limited to identifying two species.
Numbers have not yet been entered from the 7/2/04 fieldwork since not all samples have been identified yet.
Michael Charters moved up the first occurrence of Penstemon clevelandii var. clevelandii from his fieldwork on 6/7/05, and found the Silene verecunda ssp. platyota as well as noting some possible Gilia capitata just before the PCT junction.
Botanical Trip Reports
The Plant Guide In the Mile, the entry TH is for all the species in the vicinity of the trailhead, where the species are listed in alphabetical order by Scientific Name instead of in trail order.
It is possible that some of the species with a mileage given might be out of order by as much as 0.05 miles, due to inaccuracies in the mileages from different surveys and not every species being present on each survey.
The column #Pls gives the number of plants of each species on and in the area of the trail from Penny Pines to Garnet Peak. In most cases, the number gives the number of plants that can easily be reached from the trail, or seen in proximity to the trail, not just the number of plants within an arm's length from the edge of the trail, as in most older guides. Some species do not yet have abundance estimates; that column is blank for those species.
The Scientific Name is mostly in the Second Edition Jepson Manual system.
An asterisk before the common name indicates a non-native species.
See also Flora of the Penny Pines to Garnet Peak Area in Family Order, which contains links for every species to the Jepson Manual treatment and to Calphotos.

Comments On Specific Species The notes from the 6/15/04 fieldwork are not yet online.
Mentzelia dispersa. The first Mentzelia species along the trail was seen only on 5/10/03, and not keyed out. A definitive id was obtained for the plant at mile 1.37. That occurrence is not numbered, unless the previous species turns out to be a different taxon.
Quercus acutidens. This taxon is given as Q. berberidifolia in the Laguna Flora, but the leaves of the specimen here is clearly Q. acutidens in size, shape, color and trichomes. They also have a large number of Q. engelmannii trichomes present, as is typical of many specimens of Q. acutidens.
This is one of the clearest examples that this is a separate species, and not due to any recent hybridization event between Q. cornelius-mulleri and Q. engelmannii, since the nearest Q. engelmannii is at least 11 miles west, with a considerable mountain range between them and this location, and with a significant elevation difference.
