the loose rock, but finally all safely reached the rock directly above the 

 edge of the snow-field. 



The descent to the snow offered some difficulties, especially as that 

 part of the snow-field directly under the cliff had been shaded through- 

 out the day, was still frozen very hard, and was at a dangerous slope 

 leading directly to some ugly rocks. With some assistance, all hands 

 were finally safely on the snow-field beyond the point where a slide 

 would mean striking rocks below. One of our party escaped a very un- 

 comfortable slide from the spot where we first reached the icy snow 

 only by the precaution which our pathfinder had taken to first dig very 

 large footholds and to brace himself securely in these. Once at the 

 point where snow-sliding was safe, rapid progress was made, both by 

 voluntary and involuntary slides. At East Lake we shouldered our 

 packs and finished an interesting day by tramping the remaining eight 

 miles to Vidette Meadows. ^^^^^ ^^^^^ 



An Ascent of Tunnabora Peak 



On July 22, 1916, Mr. James Rennie and Mr. Walter L. Huber made the 

 ascent of Tunnabora Peak (13,593 feet) from the Sierra Club's camp in 

 the upper portion of Tyndall Creek Basin. The peak was reached by 

 following the south branch of the East Fork of the Kern River to its 

 head, thus reaching the south side of the peak which slopes to Tulainyo 

 Lake. Although all other sides of the peak are very precipitous, the as- 

 cent from the south offers no difficulties after its inaccessibility has 

 been overcome. The records of the Sierra Club indicated that no pre- 

 vious ascent of this peak had been made, but a very rusty tomato-can 

 was discovered at the summit, and by subsequent correspondence it has 

 been learned that Mr. George R. Davis, of the U. S. Geological Survey, 

 made the ascent in August, 1905. 



Tulainyo Lake, at the foot of its south slope, has a diameter of ap- 

 proximately half a mile and is at an elevation of 12,865 feet. This lake 

 is in a rocky basin on the very crest of the Sierra. A sharp ridge of 

 the main crest passes around it on the east and a less rugged ridge passes 

 along its western side. It has no apparent outlet on either side. Its set- 

 ting is unique among lakes of the High Sierra. 



Mazama Activities for the Past Year 



In addition to their outdoor activities, the Mazama Club has established 

 an educational course, begun last winter and continued during this one. 

 This consists of a lecture by some competent person each Thursday 

 evening on one of the following subjects, taken in rotation: Botany, 

 Geology, Ornithology, and Local History. The lectures are usually il- 

 lustrated with lantern-slides.
