1897 Map of Mt. Hamilton

About this map

The Lick Observatory stands as the central landmark on Mt Hamilton in this 1895 survey of the Diablo Range. The landscape is defined by a dense network of high ridges, including Oak Ridge, Packard Ridge, and Eylar Mountain, separated by deep canyons and seasonal watercourses like Smith Creek and Alameda Creek. A solitary Hotel is located along the winding road ascending toward the observatory, providing a rare sign of infrastructure in an otherwise remote terrain dominated by cattle ranching and early scientific exploration. To the south and east, the broader basins of Halls Valley and Isabel Valley contrast with the steep slopes of Steeboy Ridge. Names like Mowry Camp and Ingram Flat suggest the transient settlements and grazing outposts common to these highlands at the end of the nineteenth century.
