The lowest temperature ever recorded in the state of Oregon was -54 F (in Seneca, on Friday 10, 1933). The state’s record high temperature occurred in Pendleton on August 10, 1898, when it reached 119 F. What is the historical temperature range in the state of Oregon?

-54 + 119 = 65 (not sure if that is right)

$\displaystyle |-54 -119| = |-173| = 173$
