Yosemite Valley, June 7th, 1873. I came down last night from the Lyell Glacier, weary with walking in the snow, but I forgot my weariness and the pain of my sun-blistered face in the news of your coming. I would like you to bring me a pair or two of green spectacles to save my eyes, as I have some weeks of hard work and exposure among the glaciers this fall. They are sore with my last journey. All of the upper mountains are yet deeply snow-clad, and the view from the top of Lyell was infinitely glorious. Thanking God for thee, I say a short farewell. Kellogg has not yet appeared, nor any of the other friends you speak of. Yosemite, September 17, [1873.] I am again at the bottom meadow of Yosemite after a most intensely interesting bath among the outer mountains. I have been exploring the upper tributaries of the Cascade and Tamarac streams. And in particular all of the basin of the Yosemite Creek. The present basin of every stream which enters the valley on the north side was formerly filled with ice, which also flowed into the valley, although the ancient ice basins did not always correspond with the present water basins because glaciers can flow up hill. The _whole_ of the north wall of the valley was covered with an unbroken flow of ice, with perhaps the single exception of the crest of Eagle Cliff, and though the book of glaciers gradually dims as we go lower on the range, yet I fully believe that future investigation will show that, in the earlier ages of Sierra Nevada ice, vast glaciers flowed to the foot of the range east of Yosemite and also north and south at an elevation of 9000 feet. The glacier basins are almost unchanged, and I believe that ice was the agent by which all of the present rocks receive their special forms. More of this some other day. Would that I could have you here or in any wild place where I can think and speak! Would you not be thoroughly iced? You would not find in me one unglacial thought. Come, and I will tell you how El Capitan and Tissiack were fashioned. I will most likely live at Black’s Hotel this winter in charge of the premises, and before next spring I will have an independent cabin built, with a special Carr corner where you and the Doctor can come and stay all summer; also I will have a tent so that we can camp and receive night blessings when we choose, and then I will have horses enough so that we can go to the upper temples also. I wish you could see Lake Tenaya. It is one of the most perfectly and richly spiritual places in the mountains, and I would like to preëmpt there. Somehow I should feel like leaving home in going to Hetch Hetchy. Besides, there is room there for many other claims, and it soon will fill with coarse homesteads, but as the winter is so severe at Lake Tenaya, very few will care to live there. Hetch Hetchy is about four thousand feet above sea, while Lake Tenaya is eight. I have been living in these mountains in so haunting,
