Mine- At 14,000 feet, in the remote jungles of New Guinea is the largest gold and copper deposit in the world. Getting to that deposit and building a profitable mine was one of the biggest engineering challenges ever. In 1975 an American mining company took up the challenge and using the most sophisticated technology available, conquered the jungle and built the Grasberg Mine!

Boom & Bust When I was young, I thought that the success or failure of a gold mine was whether or not you found gold. NOPE.

I experienced my first magnitude 7.0-7.5 earthquake when I was almost 23 months old. It almost knocked me to the ground. That 1946 Vancouver Island earthquake struck Vancouver Island on June 23 at 10:15 a.m. with a magnitude estimated at 7.0 Ms[2] and 7.5 Mw.[6] The main shock epicenter occurred in the Forbidden Plateau area northwest of Courtenay. While most of the large earthquakes in the Vancouver area occur at tectonic plate boundaries, the 1946 Vancouver Island earthquake was a crustal event. Shaking was felt from Portland, Oregon, to Prince Rupert, British Columbia. This is one of the most damaging earthquakes in the history of British Columbia, but damage was restricted because there were no heavily populated areas near the epicenter, where severe shaking occurred. There were, however, a whole series of landslides in the Forbidden Plateau area there were a whole series of landslides blocked streams and rivers to create lakes. The first hikers into the area gave them great names, Landslide Lake, Rock Fall Lake, Earthquake Lake etc.; over time these natural dams were eroded to nothing, leaving nothing but fading memories of those lakes. This earthquake is Canada's largest historic onshore earthquake.[1]
Three years later, an earthquake, an M8.1, struck at 8:01 p.m. PDT on August 2, 1949 in Haida Gwaii [formerly Queen Charlotte Islands], an inter-plate earthquake that occurred on the ocean bottom just off the west coast of the main south island [Graham Island]. The shock had a surface wave magnitude of 8.1 and a maximum Mercalli Intensity of VIII (Severe).
