Along the Thousands Springs Byway, you can at least get the image of coolness from the water falls that spring from the lava cliffs above the Snake. The lava formations here are very porous and move vast amounts of water underground across the Snake River Plain. The water then emerges from the lava along this stretch of backroad to rejoin the river. Note that there is no "river" feeding these falls from above--they really do emerge from the cliff, thence the designation "1000 Springs."
The land around here is intensely agricultural and is a prime example of how the sagebrush desert can be turned into a garden spot given enough water. The fields are full of alfalfa, grass being grown for silage for the many dairy farms, corn, potatoes, wheat, all of which is being irrigated from water in the various reservoirs. Al enjoyed the feel of the area, probably harking back to his (nonexistent) farmer roots. Right about now he's longing to get back to his Apache Junction roots. A loop into Oregon, then we'll point the rig toward Arizona.
