@MasonPress4 @Volcanoes_NPS This could be the start of a “pit crater” formed by ground collapsing into voids previously filled by magma. Let’s hope the route of Hwy 11 doesn’t start to look like Chain of Crater road.
@Jasamsdestiny Look to the temp scale on the right. That shows that areas shown in the “hot” colors of yellow and orange are only 20-22 deg C (70 deg F).
