A distinctive site, Slide Mountain Vineyard is a north-facing slope
composed of basalt rock mixed with clay loam at between 1,300-ft. and
1,500-ft. elevation, well above the Missoula Flood plain, where most
area vineyards are located. Because of its location at the eastern
foothills of the Cascade Range Mountains, Slide Mountain Vineyard
benefits from good air circulation. During the summer, air movement
helps reduce temperature extremes, and during the winter it protects
vines against severe cold.
