An investigation of volcanic depressions. Part 4: Origin of Hole-in-the-ground, a maar in Central Oregon
Hole-in-the-Ground, a volcanic explosion crater, located in central Oregon is described. The morphology of the soil and rocks and the topography of the crater indicate the sequential happenings during the eruption. Geophysical measurements also indicate a domical intrusion below the crater floor, extending upward as a ring dike around the margins of the crater. The volume of ejecta was determined for four major eruptions. Varied analyses were made of the pyroclastic debris, rocks, cinders, and soil.

Selected volcanic features, part L
Volcanic features obtained from a preliminary examination of Apollo 15 orbital photographs are described. Of particular interest are the features photographed in the vicinity of the far-side crater basin Tsiolkovsky. The photographs indicate that smooth, plains-forming material is present in parts of the ejecta blanket southeast of the basin rim. A debris flow on the northwestern part of the rim is also depicted. The usefulness of near-terminator photography is evidenced by the fact that numerous flow fronts not seen in photographs taken at higher angles of illumination are clearly visible. It is concluded that the presence of so many fronts confirms the belief that multiple flows are responsible for the filling of lunar mare basins.
