OFR-638 Insert, Open File Repot, Honeyville Quadrangle

By: Kimm N. Harty and Adam P. Mckean

This 1:24,000-scale surface fault rupture map of the Honeyville quadrangle shows potentially active faults and special-study areas for the Brigham City and Collinston segments of the Wasatch fault zone mapped using primarily 0.5-meter digital LiDAR data acquired in 2013 and 2014. Fault traces were also mapped using black and white stereographic and oblique aerial photographs and previous published sources for the Wasatch fault zone and parts of the West Cache fault zone contained on the Honeyville quadrangle.

This roughly 1,000 lb block, dubbed “The Mushroom”, and containing the remains of Iguanodont and Utahraptor dinosaurs, was collected from on top of the large 18,000 lb. block of dinosaur fossils that was dragged off of a mesa in eastern Utah in the fall of 2014.
