Most of the travelers who drive through Clearlake Oaks on

State Highway 20 have no idea that a road named Round

Mountain Road actually takes you to a place called High

Valley.  The road is named after Round Mountain Volcano,

and this volcano is the reason High Valley exists today.  Many

 years ago Round Mountain Volcano erupted, damming all

drainage from the valley.  Over the centuries the valley filled

with water and the resulting lake was eventually displaced by

natural erosion.  Our vineyard rests on the dam that was laid

by Round Mountain.  This is some of the most rugged terrain

in the valley, giant lava outcrops that are miles in length and

High Valley Vineyard grows their grapes on these volcanic

soils.  High Valley differs from the rest of Lake County and

indeed most of California, because its situated east/west instead

of north/south like most valleys.  This geological anomaly

means that High Valley is able to pull in cool air from nearby

Clear Lake since there is a very low western ridge to allow

airflow.  At night the hot summer air is quenched by this cool

air, allowing the vines to ready themselves for another day of

perfect growing conditions.
