Rainbow Walk to Lukens Lake

July 06, 2013 Posted by: AH - Park Ranger (White Wolf)

A walk to Lukens Lake from White Wolf these days presents you with a panorama of colors that only deepen with your continued observation. Don’t be distracted by the meadows bubbling with Jeffrey’s Shooting Stars leaning and bending in every direction or the towering Mountain Bluebells overtaking certain sections of the trail. 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.

Sierra Sweet Bay

In Wawona and downstream, the South Fork Merced River provides habitat for a rare plant, the Sierra sweet bay (Myrica hartwegii). This special status shrub is found in only five Sierra Nevada counties. In Yosemite, it occurs exclusively on sand bars and river banks along the South Fork Merced River downstream from Wawona and on Big Creek.
