Geological Summary

The Devils Garden lava field, the NW-most of a group of three youthful-looking basaltic lava fields SE of Newberry volcano, east of the Cascade Range, contains 117 sq km of overlapping pahoehoe lava flows erupted from fissure vents at the NE part of the field. Inflated pahoehoe flows were erupted from spatter ramparts and spatter cones onto a nearly flat-lying surface surrounding several large kipukas of older rocks. The extremely fluid and inflated lavas left flows that typically increased from about a half meter thickness near the vent to about 5 m in more distal areas and have a volume of 1.2 cu km. The flows are older than the Mazama Ash (6800 years old) but are fresh-looking and relatively unvegetated. The precise age of Devils Garden is not known, but was considered to be either Holocene (Smith et al. 1978; Sarna-Wojciki et al. 1983) or about 20,000 years old (Chitwood 1994).

The Global Volcanism Program is not aware of any Holocene eruptions from Devils Garden. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Devils Garden page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The Blowouts, the spatter vents in the foreground, are the source vents of the voluminous Devils Garden lava field. Devils Garden is the NW-most of a group of three lava fields SE of Newberry volcano and contains 117 sq km of overlapping pahoehoe lava flows erupted from fissure vents at the NE part of the field. The extremely fluid and inflated pahoehoe lavas typically left flows that increase from about a half meter thickness near the vent to about 5 m in the distal portion. The lava flows are either latest Pleistocene or early Holocene in age.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
