Boar's Tusk. This is all that remains of a 2.5 million year old volcano. The rest of the volcano eroded away, this is the erosion resistant volcanic neck computer of lamproite. #boarstusk #ancientvolcanoes #volcanicneck #wyoming (at Eden, Wyoming) https://www.instagram.com/p/BrsgiH8hh85/?utm_source=ig_tumblr_share&igshid=191r7fhn7d4nb

Edge of ancient lava fields in northern New Mexico. These fields, near Grants, are some of the youngest in New Mexico at just around 3000 years old. #lavaflows #ancientvolcanoes #newmexico (at Grants, New Mexico) https://www.instagram.com/p/BnEalYkHzwV/?utm_source=ig_tumblr_share&igshid=1ngtxzg8vqisd
