Crater Mountain, an arcuate chain of peaks 3000 m or more in height, is extensively eroded to the point that its volcanic origin is almost unrecognizable. However, steep-sided valleys to the north and east are floored by lava flows and other young volcanic features. The easternmost Agotu Valley contains several small craters, cinder cones, and maars of late-Pleistocene or Holocene age (Mackenzie and Johnson, 1984). Several small cones, lava domes, and associated lava flows north and NW of the Erun Anticline may in part be Holocene in age.

The Global Volcanism Program is not aware of any Holocene eruptions from Crater Mountain. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Crater Mountain 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 broad depression above the center of this composite NASA Landsat image of Papua New Guinea (with north to the top) is Crater Mountain. Although this arcuate chain of peaks 3000 m or more in height is extensively eroded, steep-sided valleys to the north and east are floored by lava flows and other young volcanic features. The Purari River cuts across the bottom of the image, and the smaller Pio River parallels it to the north, south of Crater Mountain.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
