Yosemite National Park, CA (Jun 5th - Jun 11th 2016)

Yosemite National Park stretches across the western slopes of the Sierra Nevada mountain range, spanning nearly 1,200 square miles. Our nation's third national park, Yosemite is widely known for its magnificent rock formations, grassy meadows, crystal-clear streams, majestic waterfalls, rushing rivers, ancient giant sequoia trees, and abundant wildlife. Over 90% of the park is designated as wilderness, providing a phenomenal variety of growing conditions and habitat for more than 1,450 native plant species.

Our ninth year service project will take place in the beautiful Hetch Hetchy section of the park. Carved by glaciers and drained by the Tuolumne river, the Hetch Hetchy Valley lies in the northwestern part of Yosemite National Park and contains some of the tallest waterfalls in North America: Wapama Falls, at 1,700 ft (520 m), and Tueeulala Falls, at 840 ft (260 m). Our continuing project in Yosemite is removal of several species of invasive weeds such as wooly mullein, bull thistle and western salsify. These invasive plants have the potential to rapidly displace native plants, alter fire regimes, significantly alter ecosystem structure and negatively affect associated wildlife throughout Yosemite.

Project participants will hike in approximately 6.5 miles around the northern shore of the Hetch Hetchy reservoir to Rancheria Falls and set up a basecamp. The hike in is a scenic treat with a modest elevation gain that includes hiking over a dam, through a short tunnel, across a few foot bridges, under some spectacular waterfalls, and maybe even a mist rainbow or two. From our basecamp we will hike approximately 3 miles to and from grassy meadows in the area each day to work. We'll also likely conduct a day of campsite restoration in the backpackers campground at Rancheria Falls. The Park Service will provide pack support to carry the tools, food and commissary gear to camp.

Come spend a week in beautiful Yosemite National Park and give something back to our nation's wild lands with Wilderness Volunteers!
