I used Globalmapper (more on that later) to quickly create this shaded relief image of the study area. Are most of the lava platforms that are so evident in this image related to lava-dams? The various volcanic structural forms in this image are really very striking. If it turns out that all or most of these features reflect late Neogene lava-water interaction, this is a fairly significant landscape-forming process in this region...the distribution of these features on the landscape record the progressive incision of the Owyhee River over a very long time, no?
