After a refreshing soak, we hit the road. Not a hint of jet lag or sleep deprivation remained. We drove south down Hwy 1, Iceland's Ring Road that circumnavigates the island. An army of basalt boulders, green with lichen, marched in endless columns towards the horizon. A band of wild horses sprinted alongside us, caramel brown with blonde manes, their speed nearly matching our own. Geothermal vents dotted the landscape, thick white plumes fuming into the sky like a locomotive chuffing uphill.
An hour later, we arrived in Selfoss, a charming town on the Ölfusá river. Foss means waterfall, we read in a guide. They pop up like every thirty feet in Iceland: Gulfoss, Skógafoss, Kirkjufellsfoss, Dettifoss...but we couldn't find a single one in Selfoss.
"It's Selfoss. Maybe it's a riddle: the waterfall is within us," I suggested to my wife. She said I needed sleep. We compromised and drove a little farther to Seljalandsfoss, a 200-foot sheet of water with a muddy path leading behind the falls.
