Road work at Beryl Spring to divert around hydrothermal area in 1942

Beryl Spring is a hydrothermal area in some restrictive topography! The road from Norris Geyser Basin to Madison Junction follows the Gibbon River through a tight valley. With not much of a choice, the road threads between the river and Beryl Spring over some exceedingly hot ground. It takes a feat of engineering to keep the road drivable through this area, and sometimes nature has the final say, as in 1942, when this National Park Service photo was taken. Don't fret, the road is now passable by auto and bison.
