View from the crest of the Mono Craters is looking toward the north. Mono Lake is visible on the right side of the photograph; the Sierra Nevada are the snow-covered peaks on the left. The original blocky surface of the red-colored lava dome sticks up through tephra erupted from one of the North Coulee vents; a remnant of a crater rim cuts through the photograph. The blocky lava outcrops are also active fumaroles releasing water vapor (steam) and carbon dioxide gas.
