I explored the Redmond Caves in Redmond, Oregon (near #KRDM Airport, served by Alaska, AA, Breeze, Delta, United). These are some small lava tubes worth a quick stop. Bring a flashlight/headlamp and a spare when exploring any cave.
If you think Redmond sounds familiar, this is not the place. You're probably thinking of Redmond, Washington in the Seattle metro area where Microsoft HQ is. This Redmond is in Eastern Oregon.
