Humboldt Ecological
Province
A segment of the northern
portion of the Great Basin of North America. It is in southeastern
Oregon. It is characterized by long, generally north-to-south
mountain ranges and valleys with ancient lake terraces and fans
lying along the footslopes. Elevations in Oregon range from
4,025 at Alvord Desert to 8,545 feet on the Pueblo Mountains.
Immense
sodic bottomlands and mountain ranges near the Nevada border.
Continuous ancient-lake terraces and fans appear as a lighter-color
formation between the bottomlands and the mountains.
Managed
natural desert shrub range on very stony ancient lakeshore terraces
and fans are typical.
Ancient-lake
terraces, such as Alvord Lake basin, along the eastern footslopes
of Steens Mountain are typical.
