Thor's Well is a relatively large diameter (10'/3m) blowhole along the Oregon coast of the Pacific Northwest. The interesting feature of Thor's Well is that the surrounding rock is relatively bowl shaped. This shape forces much of the water that was ejected by the blowhole to retreat back into the same blowhole it was ejected from. Yachats Oregon, USA
The largest wooden hulled gold mining bucket dredge in North America was run by electricity drawn from 31mi(50km) away. Designed by the Marion Steam Shovel Company, and built for the Canadian Klondike Mining Company in 1912, the dredge processed 18,000 cubic yards of material a day. The tailing piles these dredges make, scar the landscape for miles. Decommissioned in 1959, the dredge had unearthed 9 tons of gold grossing $8.6 million. It is now a historic site.
