There is black gold in them thar hills...

On our way home on December 30th from downhill skiing at Worsley, Alberta, we took Petro Canada road through the Boundary gas field. You normally get oil and gas from the same location. The countryside around here is dotted with gas wells that are just a valve and a hut, but every so often you get a pumpjack, an engine hut and a tank for it to fill (as pictured here). Pumpjacks are used on old low gas pressure wells and literally suck the oil out of the ground. This one has an old single cylinder diesel donkey engine doing about 100 rpm making the pump go up and down.
