The entire region above Yosemite and as far down as the bottoms of Yosemite has scarcely been touched by any other inundation than that of ice. Perhaps all of the past glacial inundation of every kind would not average an inch in depth for the whole region. Yosemite and Hetch Hetchy are lake-basins filled with sand and the matter of moraines washed from the upper cañons. The Yosemite ice, in escaping from the Yosemite basin, was compelled to flow upward a considerable height on both sides of the bottom walls of the valley. The cañon below the valley is very crooked and very narrow, and the Yosemite glacier flowed across all of its crooks and high above its walls without paying any compliance to it, thus: [drawing here]. The light lines show the direction of the ice-current. Yosemite Valley, March 30, 1873. Your two last are received. The package of letters was picked up by a man in the valley. There was none for thee. I have Hetch Hetchy about ready. I did not intend that Tenaya ramble for publication, but you know what is better. I mean to write and send all kinds of game to you with hides and feathers on, for if I wait until all become one, it may be too long. As for Le Conte’s Glaciers, they will not hurt mine, but hereafter I will say my thoughts to the public in any kind of words I chance to command, for I am sure that they will be better expressed in this way than in any second-hand hash, however able. Oftentimes when I am free in the wilds I discover some rare beauty in lake or cataract or mountain form and instantly seek to sketch it with my pencil, but the drawing is always enormously unlike the reality. So also in word sketches of the same beauties that are so living, so loving, so filled with warm God, there is the same infinite shortcoming. The few hard words make but a skeleton, fleshless, heartless, and when you read, the dead, bony words rattle in one’s teeth. Yet I will not the less endeavor to do my poor best, believing that even these dead bone-heaps called articles will occasionally contain hints to some living souls who know how to find them. I have not received Dr. Stebbins’ letter. Give him and all my friends love from me. I sent Harry Edwards the butterflies I had lost. Did he get them? Farewell, dear, dear spiritual mother! Heaven repay your everlasting love. JOHN MUIR. April 1st, 1873. Yours containing Dr. Stebbins’ was received to-day. Some of our letters come in by Mariposa, some by Coulterville, and some by Oak Flat, causing large delays. I expect to be able to send this out next Sunday, and with it Hetch Hetchy, which is about ready and from this time you will receive about one article a month. This letter of yours is a very delightful one. I shall look eagerly for the rural homes. When I know Dr. Stebbins’ summer address I will write to him. He is a dear young soul, though an old man. I am “not to write” therefore. Farewell with love.
