Card is titled: “939 / Triple Tunnels in Shoshone Canyon on Cody Road / Eastern Entrance to Yellowstone National Park / 2A-H685.”

Printed on back of postcard:

TRIPLE TUNNELS
The wonders of the Yellowstone trip begin on entering Shoshone Canyon, the mighty gorge through which the Shoshone River takes its course.  The walls of the canyon are nearly perpendicular and yet along the side of Rattlesnake Mountain a road for a length of 8 miles has been blasted from solid rock.  In many places the road passes through tunnels in the granite walls.
