North Dome

Mousetail Ivesia is in full bloom on North Dome. A member of the rose family, its common name relates to its narrow, velvety leaves which resemble mouse tails. Its tiny white blossoms balance atop thin, branching, almost-naked stems and today were shaking in the strong wind that tried to steal my hat. These easy-to-miss plants are part of the unique flora associated with the gravelly tops of Yosemite's granite domes. Please be careful where you step out in these special places!

Trail to North Dome from Porcupine Creek Trailhead

The mostly-dark forest floor of the first part of the trail to North Dome from the Porcupine Creek parking area is dominated by fallen trees, branches, rotting red fir logs, and stumps in various shades of brown and gray.  All the more striking is this snowplant emerging from a seemingly monotone background of duff. With no chlorophyll at all to do normal plant-like things, it is probably getting its energy to flower (and eventually fruit) through a network of fungi in the soil that are themselves connected to the roots of nearby trees. This bright-red flowering plant is a strange little outgrowth of the forest internet!

    Interesting blog! My husband and I first encountered snow plant on our hike to North Dome a couple of years ago and were so perplexed by its bright red color! Now it's one of our favorite plants to find in the high country in the early summer.

Vernal and Nevada Falls

In Yosemite Valley, dropping over 594-foot Nevada Fall and then 317-foot Vernal Fall, the Merced River creates what is known as the “Giant Staircase.” Such exemplary stair-step river morphology is characterized by a large variability in river movement and flow, from quiet pools to the dramatic drops of the waterfalls themselves.
