The snow-covered mountains at the right-center, lying between the Mess Creek (left) and Little Iskut River (right) drainages, are in the Spectrum Range, one of four large composite volcanoes making up the Mount Edziza-Spectrum Range volcanic complex. Holocene pyroclastic cones and lava flows are found on the NW and SW sides of the Spectrum Range. The Mount Edziza complex appears at the top of this image (with north to the upper left), west of snow-covered Nuttlude and Kakiddi lakes. Elongated Kinaskan Lake is at the upper right.
