Geologists produce Teton fault map for download

IDAHO FALLS, Idaho (AP) — A new fault map from the Wyoming State Geological Survey shows the Teton Range is still growing, with its fault line getting ever-so-slightly taller each year.

The Post Register in Idaho Falls, Idaho reports the map was created in an effort to study and track the fault line, and it’s now available for a free download on the Wyoming State Geological Survey website .

Geologists with state and federal agencies, academic organizations and consultants worked to create the map using a surveying method called light detection and ranging, or LIDAR. The method involves shooting light — in the form of a pulsed laser — at the ground from an aircraft to get a high-resolution, detailed image of the earth’s surface.

The map’s lead author, Mark Zellman with BGC Engineering, said the LIDAR equipment was able to capture greater detail than previous maps, which were limited by dense vegetation and rugged terrain.

“The new fault map represents a state-of-the-art
