This view from Dutchman Trail was taken on the red line trail (below) between Black Top Mesa (out of view, on left) and Bluff Springs Mountain (right), on the approach to White Rock Spring and LaBarge canyon (the large canyon at the north end (left) of the red line.
Those cliffs above the Dutchman Trail (in red from the push pin “Dutchman Terrapin Trail Junction”) climb 670 feet in 0.2 mile. Fifteen minutes after starting I stopped to photograph a group of wildflowers.
The bright yellow flowers on right are a member of the pea (Fabaceae) family named Wright’s Deervetch (Acmispon wrightii) I am able to pick it out from many similar flowers due to the characteristic narrow leaves with small hairs. These start out yellow, turning to red with age eventually forming brown seed pods. Mexican Poppy (Eschscholtzia californica) to the right.
The small white flowers are Chickweed (Minuartia macrantha) of the family Carnation (Caryophyllaceae).
Here is the topographic map with Terrapin Trail (yellow) meeting Dutchman Trail (orange) to the right of Upper Black Top Mesa Pass, bottom center
The beetling cliffs off Bluff Spring Mountain loom over where Terrapin and Dutchman trails meet. Patches of yellow are Mexican Poppies blooming on the talus slope. Terrapin Trail climbs the ridge, to right. Here is where I caught up with mounted expedition members, the spotted rump of an Appaloosa figures prominently next to the signpost.
Terrapin Trail almost immediately starts a climb up to an eponymous pass between Bluff Springs Mountain and Weavers Needle. From here, it is the best way into the mountain. The trail name is a misnomer, as terrapin (Malaclemys terrapin) turtle habitat is near the ocean. There is a desert tortoise (Gopherus agassizii) you might encounter during the rainy season as they are otherwise inactive.
