High-resolution digital elevation dataset for Newberry Volcano and vicinity, Oregon, based on lidar survey of August-September, 2010 and bathymetric survey of June, 2001

Metadata Updated: October 28, 2023

Newberry Volcano, one of the largest Quaternary volcanoes in the conterminous United States, is a broad shield-shaped volcano measuring at least 60 km north-south by 30 km east-west with a maximum elevation of more than 2 km above sea level. It is the product of deposits from hundreds of eruptions, including at least 25 in (approximately) the last 12,000 years (the Holocene Epoch). Newberry Volcano has erupted as recently as 1,300 years ago, but isotopic ages indicate that the volcano began its growth as early as 0.6 million years ago. Such a long eruptive history together with recent activity suggests that Newberry Volcano is likely to erupt in the future. This DEM (digital elevation model) of Newberry Volcano contributes to natural hazard monitoring efforts, the study of regional geology, volcanic landforms, and landscape modification during and after future volcanic eruptions, both at Newberry Volcano or elsewhere globally. Acquisition of these high-precision, airborne lidar (Light Detection And Ranging) data was funded as part of the American Recovery and Reinvestment Act (ARRA) of 2009. Data were collected through the Oregon LiDAR Consortium, administered by the Oregon Department of Geology and Mineral Industries (DOGAMI). Watershed Sciences was contracted to collect 500 square miles of high-precision airborne lidar data to produce a digital map of the ground surface beneath forest cover. The lidar-derived DEM is amended to include bathymetric surveys of East Lake and Paulina Lake. The bathymetric surveys were performed in June, 2001 by Bob Reynolds of Central Oregon Community College, Bend, Oregon. The bathymetry is mosaicked into the DEM in place of the lidar derived lake surfaces. This release is comprised of a DEM dataset accompanied by a hillshade raster, each divided into eighteen tiles. Each tile’s bounding rectangle is identical to the extent of the USGS 7.5 minute topographic quadrangles covering the same area. The names of the DEM tiles are eleven characters long (e.g., dem_xxxxxx) with the prefix, "dem", indicating the file is a DEM and the last seven characters corresponding to the map reference code of the quadrangle defining the tile's spatial extent. Hillshade tile names are denoted by the prefix "hs", but are otherwise identical to the DEM they are derived from.
