The vineyard is in planted on a south aspect hillside, that is largely blow sand  and loess on top of fractured basalt  The soil depth ranges from 1' at the top of the hill to 10' at the bottom.  This soil type does not have a large water holding capacity, requiring careful moisture monitoring.  The soil  stays fairly loose and well drained, allowing for easy root expansion.  This is one of the warmer vineyard sites in Washington State, with a lot of similarities to the Red Mountain AVA, 5 miles to the west.
