I promised another bench and after looking at the photos, I realized I have photos of two benches.
They were encountered on the day we drove from the west sea to the east sea across the big island of Hawai'i, a distance of 77 miles between the big mountains Mauna Kea and Mauna Loa. We started at sea level, rose to 9000 feet and back to sea level. And then returned along most of the same path. The target destination was Rainbow Falls, a multi-falls water falls in the city of Hilo. We had a problem or two finding the site, but stopped in a school parking lot to look at the map. A school security guy came up to the car and asked what we were looking for, and we told him Rainbow Falls. He told us the way, but warned that here may not be any water flowing over it, because it had been dry lately. When you live in Hawaii, I guess you don't visit the tourist attractions often, because when we arrived at the falls there was plenty of water flowing over the precipice. Just up the river from Rainbow Falls there is another attraction - Boiling Pots. It's a canyon with rocks over which flowing water seems to bubble and roil in a kind of Hawaiin rapids. In the parking lot by the Pots the lava benches sat - unused.
There was another similar bench at the same site. Lava rocks and some sort of fungal growth or lichens, perhaps, are evident.
A map of the trip across the big island to visit Hilo looks like this.
Back in the land of icy streets and wind chill, it was another day considered life threatening. It was -9º F. this morning, but has risen to 1º F. I ignored the danger and went off this afternoon to smack tennis balls at Fort Snelling. I had not completely lost my coordination and it was quite satisfying to crunch some forehands after 18 days of self imposed rest.
