Despite the 100 year gap in eruption, the summit caldera was very active with some areas reaching 800°F and dense sulfur-gases. https://images.squarespace-cdn.com/content/v1/587693636b8f5bdeb6e82c0f/1484597042076-XJRXPJ37D7MIJJ4780XJ/image-asset.jpeg Research Ground up minerals were sealed in Teflon containers with varying amounts of sulfuric acid and heated at a range of temperatures and for up to 6 months. https://images.squarespace-cdn.com/content/v1/587693636b8f5bdeb6e82c0f/1484596729530-MXC0PIZ1VPUD4PCJ4B2Y/DrainageRight.JPG Research Cerro Negro is a young (~150 years old) cinder cone in western Nicaragua outside of León.

The flat middle area (pinkish) is an outwash basin or drainage area. https://images.squarespace-cdn.com/content/v1/587693636b8f5bdeb6e82c0f/1484596905783-WJYNABY1RRPGU53H23KC/image-asset.jpeg Research Momotombo Volcano is a traditional stratovolcano, a few hundred years old and ~1300 m tall (4,300 ft). We each the summit caldera by climbing up an old lava channel, which took about 3 hours (just as long coming down too!). https://images.squarespace-cdn.com/content/v1/587693636b8f5bdeb6e82c0f/1484597122585-L4PSI00KXH8Q7MWL6J1W/image-asset.jpeg Research The most dominant secondary minerals formed were Ca-sulfate, either anhydride or the hydrated form gypsum. The macroscopic crystals took needle-like forms (different lengths and thicknesses) and dried white. https://images.squarespace-cdn.com/content/v1/587693636b8f5bdeb6e82c0f/1484347392145-FTNPT1ZDGD8TMTF5VG5S/Figure3_color_black+decrease.jpg Research Features on Lost Jim Lava Flow.

Depressions on Mars tend to be bigger and clustered, but may still represent lava-ice interactions. Difference could be the results of ground ice concentrations, insulating ground covers, or lava emplacement mechanisms. https://images.squarespace-cdn.com/content/v1/587693636b8f5bdeb6e82c0f/1484347200505-G7LRKGPJK2Q52F08DSIG/LostJim.jpg Research Lost Jim Lava Flow on Seward Peninsula, AK is a ~2000-year-old pahoehoe lava flow. This area also hosts ice-bearing permafrost. The interaction of the two would have resulted in unique features, specifically collapse depressions.
