Thanks for all the information. If anyone has Montana related Peltrolia or station e-pics please feel free to forward them to me at bgoodman@mt.gov. FYI-there is a very good 2-part article in Montana Magazine on the history of petroleum refining in Montana that appeared in Spring/Summer 1998.

There was a mention of Husky in one reply. They were originally based out of Wyoming until they sold off most of their U.S. assets and retreated to Canada. They later re-entered the US market and also aquired Earl Clack's operations in the mid-1950s. They continued to operate many stations in MT until the early 1970s and of course are still widespread in Canada. Thanks. Brian
