1958 Map of Topaz Mountain

About this map

The Kenosha Mountains and Lost Creek Wilderness dominate this high-altitude landscape in Park County, where the North Fork South Platte River carves a deep valley through the northern section of the Pike National Forest. This 1958 field-checked survey documents a period when the area was primarily used for resource extraction and seasonal grazing, as evidenced by the presence of the Northup Lumber Camp and Lost Park Cow Camp. Topographic interest centers on high summits like Topaz Mountain and North Tarryall Peak, alongside the striking recovery area of the Hourglass Burn. Access into this backcountry was facilitated by the Lost Park Road and historic paths like the Hooper Trail, connecting isolated water sources such as Bonis Spring and Cabin Spring across the rugged gulches and peaks.
