Our adventurous group left Catlin Saturday morning to go to the lava tubes southeast of Bend and hike at Smith Rock State Park. We drove down the Gorge to get to Bend, and along the way got to see some cowboys moving their herd of cows down the road. After a spectacular drive out of the green forests of the Willamette Valley into the yellow grasslands of Central Oregon, we arrived at our first cave, Boyd Cave. Although many of the caves are closed for bat habitat restoration, we were allowed to go into Boyd Cave. After donning helmets and headlamps, we explored the narrow passageways, expansive rooms, and rocky scrambles of the lava tube. We even turned out all the lights and listened to the profound silence only found in a cave. At the very end of the cave we squeezed into a tiny tunnel before retracing our steps back to daylight.
