The forces that helped form Ranch at the End of the Road vineyard and Red Mountain AVA geology were truly gigantic. The deep bedrock of most of the Columbia Basin is basalt, formed from the massive lava out flows caused by intense volcanic activity. On top of the basalt lie layers of sediment deposited by repeated ancient floods. On top of the sediment are layers of sand and silt from eons of erosion and weathering. The high alkalinity and high calcium carbonate content produce wines of incredible structure and longevity.
