Sierra Nevada Resurvey

July 21 – July 26, 2014

This is a week of scientific survey work, attendees are volunteer botanists, students, research scientists or previous GLORIA workshop attendees. If you have high altitude experience, are a reasonably competent botanist, are familiar with GLORIA-style surveys, we would love to have you!


Accommodations: We will be car camping at undeveloped campgrounds at Warren Fork Campground and Silverpine Lake. You will need to bring ALL other supplies for camping, including food, stoves, tents, sleeping bags, etc. Water is available but will need to be filtered or boiled. The access road to Silverpine Lake is 4WD (high-clearance 4WD vehicles are necessary, heavy duty tires recommended, Subaru’s are not OK).  If you do not have a 4WD vehicle, please let Adelia know, and we will arrange to shuttle you and your belongings to the campground.

Other accommodations: There is a developed campground about 3 miles away from Silverpine Lake (Trumball Lake Campground) and motels available in Lee Vining. There are two, minimally developed, unsigned USFS campgrounds with toilets, bear boxes, and tables (no water) in the Virginia Lakes area closer to the Dunderberg sites.  The upper unit is accessed by continuing west on the main paved Virg Lks Cyn rd 0.1 mi W of the Green Creek-Dunderberg Mdw Rd jct.  Turn left on FR 139 to access the upper campground.  The lower unit is accessed about 2 miles below the Green-Creek-Dunderberg Mdw Rd jct, also turning left on FR 139 to access campsites (again no sign about campground).  Oddly enough, FR 139 does not connect between the two units, although it would seem it should.  These are nice sites.

Price: No charge, gratis, free.

Food: There may be some impromptu group meals, but we are asking to people to do their own shopping and bring their own food.

Sites:  The GLORIA Sierra Nevada Target Region consists of 4 summits.  The Granite Lakes summit is located off Tioga Pass Rd, right at the edge of Yosemite National Park, and is closest to the Warren Forks campground.  The other 3 summits are ~ 9 miles north, in the Dunderberg Peak area.  We will be car camping at Silverpine Lake for the FIRST half of the week to access the Dunderburg summits.

Directions to Silverpine Lake / Dunderberg Sites:
–From hwy 395 North, continue through Lee Vining and past Mono City. Go up the switchbacks to Conway summit. At the top of Conway summit, there is a paved road called Virginia Lakes Rd. Turn left (west) here and continue 4.5 miles.
–Turn right (north) on the “Dunderberg Meadows RD”, also signed ‘Green Creek’.  This is a high-grade dirt road, keep right on the first part of this road and continue 1.3 miles.
–Turn left on a 2-track (2WD, sedan-ok) dirt road. This is a 3-way jct: take the north-trending 2-track road (in other words take the more gentle left turn, not the hard left), which is Forest Service rd # 32178. Continue 0.3 miles.
–Turn left onto the high-clearance 4WD road to Silverpine Lk, which is Forest Service rd # 22317. Continue on forest road #22317 until you reach Silverpine Lake.  To park 2WD sedans for a shuttle, rather than turning left onto the high-clearance road, continue straight about 100’ to a parking spot at the forest border.

Camping at Silverpine:  We will be camping on the E side of the lake – at the lake, you can follow the road toward the north, which skirts the east side of the lake (toward Kavanaugh Crest), and before the outlet of the lake (dry), there is a bench in the white bark pine forest; we will be camping on the E of the road – there are many sites.  There may be bugs here, so bring anything you need to deal with high-elevation mosquitos and ALL other camping equipment, supplies, food, etc.

Directions to Warren Fork Campground:  From hwy 395, go up the Tioga Pass road (120). Continue up the road until the first major switchback. At the switchback is a sign marking 9000ft elevation. There is a dirt parking lot on the left (south) side of the road here. Park here and cross the road to the Warren Fork Walk in campground.  From the west (hwy 120 through YNP), exit the Park through Tioga Pass. Go down past Ellery Lake (~9500ft) until you reach the 9000ft elevation sign. Turn right here into a dirt parking lot. Park here and cross the road to the Warren Fork Walk in campground.

Camping at Warren Fork: This is an old USFS campground that is still in use but is unmarked.  The road is no longer open so you have to walk up the road 5-10 min, there are tent sites and a few picnic tables.  There are often climbers camped in the parking lot area just off the road, but there is plenty of parking and we’ll be camping in at the walk-in site.  This site is often buggy!  Bring bug supplies.
