Crater Lake Geologic Guide and Recreation Map, 1 double-sided sheet, water-resistant paper, 36 x 18 inches, by Daniel E. Coe.

This double-sided folding map on water-resistant paper shows all Crater Lake National Park trails including the Pacific Crest Trail as well as highways and park services. Trail distances and elevations are lidar derived. The geology of Crater Lake, including the eruptive history, is described in text, photographs, and charts.

This map for the outdoors enthusiast uses a laser-based terrain elevation technology called lidar (light detection and ranging) as the base.

Lidar (light detection and ranging) is a remote sensing technique similar to radar that uses light pulses instead of radio waves. Lidar is typically “flown” or collected from planes and rapidly produces a large collection of very dense and accurate elevation points (up to 500,000 per second) over a large area. The product can be used to generate three-dimensional representations of the Earth’s surface and its features.

The Oregon Department of Geology and Mineral Industries (DOGAMI) uses lidar to create new-generation maps that are more accurate and comprehensive than any in the past. DOGAMI, via the Oregon Lidar Consortium, is continually acquiring new lidar data throughout Oregon.
