Cogswell 1950 "Journal" 12 "Lodge" -- see Sugar Bowl Lodge "Mary Lake" -- see 1/3 mi. S Donner Pass Martis Valley, 5800-5920 ft., 1 1/2-4 1/2 mi. ESE Truckee, Nevada Co., Calif. (our "coverages" only from road which traverses the valley enroute from Lake Tahoe to Truckee). VEG. TYPES: Great Basin sagebrush formation (Art- emisia tridentata, Purshia tridentata, & other shrubs) grassy swales near stream; arid conifer forest (Pinus, Jeffreyi, P. murrayana). VISITS: "enroute" thru valley on July 12, 26; Aug. 9, 23. Mt. Judah -- 8243 ft. peak on Sierra crest, 1/3 mi. E, 1 1/3 mi. S Donner Pass (see map). Not visited, but certain notes on birds seen near its lower slopes refer to it. Mt. Rose, 2 mi. S, 1 mi. E of (or 2 1/3 mi. SSE), 8700- 8900 ft., Carson Range, NE of Lake Tahoe, Washoe Co., Nevada. -- our observations limited to immediate vi- cinity of the road from Galena Creek Camp (q.v.) over the pass near here (8933 ft.) & down to Lake Tahoe; this high altitude stop of our all day trip was merely a brief excursion away from the road near an 8730 ft. Bench Marker just N of the pass. VEG. TYPES: subalpine conifer forest (Pinus murray- ana, Pinus albicaulis, Tsuga mertensiana, Pinus monti- cola) with extremely little in the way of understory; ground quite gravelly (decomposed granite); one small riparian thicket (Salix sp.) by a water seep. The summit of Mt. Rose is visible from here, with succes- sively higher zones of vegetation, including good krummholz (Pinus albicaulis) & a timberline. VISITS: June 27; July 12, 26; Aug. 9, 23. (I climbed this mountain from near here on July 11, 1948; birds recorded on that trip are listed in my personal roll book). (Ne L. Van Norden) Norden R.R. Sta., near, 6800 ft., approx. on boundary of Nevada & Placer Cos., 2 mi. W Donner Pass, Calif. VEG. TYPES: forest & border, riparian thickets (few) of same type as listed under Lake Van Norden (q.v.) only the lake & open meadow are not represented here, although a corner of the latter comes up to the dirt road paralleling the RR on the S at a point where there is a sheep corral (See Sialia currucoides, Certhia familiaris). VISITS: July 6 (twice) -- plus more briefly on each of the major visits to Lake Van Norden.
