Geography and Topography questions....?
Where in Oregon do we find basin and range topography? What is the longest fault-block mountain in the state that is part of the system?
You dont have to answer both but any input is great!
Thank you so much.
It is the very southern and eastern half of the state that has the basin/range topography. Here is a map showing the boundaries of the basin and ridge province.

Several excellent photos of Oregon's basin and range topography can be seen here:

Steens (mountain) is the longest fault block mountain in Oregon. It is 30 miles long and reaches a height of 9,733 feet and its east side drops 5,000 vertical feet into the Alvord Desert. Good photo here"
