Grading is going quickly today, so time to ponder crafting a new volcano for my tissue box collection. Here's a hillshade of the likely candidate courtesy of the awesome folks @opentopography.org making USGS data accessible to educators and artists like me. So, what is the mountain's name?

Flying through Death Valley, from south to north, to illustrate the differences between the alluvial fans on the eastern and western sides. Flow accumulation maps draped over a digital elevation model. Data: USGS 3DEP (download it from @opentopography.org); processing with @whiteboxgeo.bsky.social

Kind of cool/weird visualization of an airborne lidar point cloud covering the UW Madison campus. The two tall buildings are AOS in foreground, Van Hise in the distance. Points shaded by classification. Fairly low res but will work for a demo. Data from USGS via @opentopography.org
