Pacific Tree Frog: Pseudacris rigilla

September 07, 2013 Posted by: CF - Park Ranger (Yosemite Valley)

Take a closer look on your hands and knees at the 4 different species (and colors) of little violets blooming or the herds of pink elephants (Elephant’s Head) gathering higher up above the ground in a few special places. Don’t miss the Green Rein Orchids as you bound along the trail towards the glowing Sierra Butterweed.
