The journal of nature-lover John Muir who spent the summer of 1869 walking California’s Sierra Nevada range. From French Bar to Mono Lake and the Yosemite Valley, Muir was awestruck by everything he saw. The antics of the smallest “insect people” amazed him as much as stunted thousand-year old Juniper trees growing with inconceivable tenacity from tiny cracks in the stone. Muir spent the rest of his life working to preserve the high Sierra, believing that “the clearest way into the Universe is through a forest wilderness.” John Muir (1838-1914) was born in Dunbar, Scotland and grew up in Wisconsin, USA.
