Oil Springs, Nr. The Canadian Museum of Nature has plenty of neat things to see though it is woefully inadequate on Petroleum Geology implying that the centre of the Oil Industry is the Williston Basin and that carbonates are permeable while sandstones are impermeable. They have a pamphlet describing the exhibits but it was only available in French when I visited. I couldn't find much information on the local geology. Don't miss the Tilston Limestone from the Red River Formation of Manitoba in the Parliament Building along with the other old fossils.
Tours are free.
There are also caves in the Gatineau park that can be hiked to. Well worth taking the day and exploring the Spirit Lake Memorial Highway. Superbly preserved Miocene ginkgo trees that were entombed by molten lava. Interesting Interpretive Centre and hiking trails - though the area gets very hot in summer.
