Not long ago a friend sent me photos of a huge cave entrance entirely composed of tall basaltic prisms: roughly hexagonal columns which are sometimes formed as basaltic lava cools. The cave was located near a pueblito called Los Reyes, located 7.5 kilometers northeast of San Sebastián del Oeste, as the crow flies. The only problem, I had heard, was the road, which was said to be in bad shape, requiring four-wheel drive and nerves of steel to put up with hours of negotiating blind curves overlooking deep chasms. Amazingly, I found someone interested in going to check out that bad road: my neighbor Josh Wolf, who said he needed a break from sitting in front of a computer screen day after day. “My family and I are up for an adventure this weekend,” he told me.
