Abstract

We present new LiDAR images and morphological analyses of the Inyo Domes and Inyo Craters volcanic chains in the northwest margin of the Long Valley caldera, eastern California. The data were collected in a single N-S swath in the summer of 2016 by the National Center for Airborne Laser Mapping (NCALM) through a research seed grant. These data provide the most accurate digital elevation models and topographic maps available of the complex surface morphologies of the five Inyo Dome silicic lavas: Wilson Butte, Obsidian Dome, Glass Creek Dome, and North and South Deadman Domes. The four large phreatic craters of the Inyo Craters (Summit, West, North Inyo, and South Inyo), along with many smaller, forested craters in the Inyo Craters and Inyo Domes, are revealed in new detail and their volumes better quantified. This presentation highlights the advances in mapping young, forested volcanic features through airborne laser scanning, and demonstrate that a lot can still be learned about even the most often visited features.
