Geologic hazards, geomorphic features, and land-use implications in the area of the 1976 Big Thompson flood, Larimer County, Colorado. 4 plates (1:12,000). Digital PDF download. EG-10D

The intense rain and flooding in the Big Thompson Canyon area on July 31- August 1, 1976, activated or accelerated several geologic processes. Not only was the main canyon affected, but also tributaries and drainages. This mapping delineates both localities where hazardous processes took place during this storm and places where similar adverse events could reasonably be expected to occur sometime in the foreseeable future.

Plates 1 through 4 include: 1) the index with introductory text; 2-3) the map west and east halves; and 4) geomorphic features formed by flooding on the Lower Big Thompson River, July 31- August 1, 1976.
