What is the boundary for a deer to be considered a cascade blacktail?
The 2009 regulations defines a Black-tailed Deer as "Any member of blacktailed/
mule deer (species Odocoileus hemionus)
found west of a line drawn from the Canadian
border south on the Pacific Crest Trail and along
the Yakama Indian Reservation boundary in Yakima
County to the Klickitat River; south down Klickitat
River to the Columbia River."
