This has been a labor of love and a lifelong dream of mine as long as I've been a flight simmer. Now, that dream is becoming a reality, and I'm very soon going to share that dream with the Flight Sim community!
For the last month and a half, I have been hard at work creating one of my most favorite areas for FSX. Only with this, it requires a travel back in time (not quite within the sim, but metaphorically speaking)
Before the spring of 1980, Mount St. Helens in Washington State was a crown jewel. Its near-perfect symmetrical cone at 9,677 feet elevation earned it the nickname "America's Mount Fuji" and was the subject of postcards and Christmas trinkets all over the Pacific Northwest. Spirit Lake, nestled just three miles from its base on the north side, was one of the most popular tourist destinations in Washington State, and a very popular spot for recreational boating and fishing. Adorning the lake were a number of camps, lodges, and a United States Forest Service ranger station serving as an entry point into the Gifford Pinchot National Forest. On the northeast base of Mount St. Helens, a backcountry ski area offered winter ski enthusiasts with dozens of acres of prime skiing territory.
At the center of it all, was an eclectic lodge owner - Harry R. Truman. His Mount St. Helens lodge was the most popular tourist destination in the area. With over 13 cabins, a boat house, and a recreation hall, his lodge was the centerpiece of a vast area of recreation across two Washington counties. Truman himself was an area legend.
That all changed in an instant on May 18, 1980, when an eruption over 500 times more powerful than the Hiroshima atom bomb leveled 230 square miles of forest and turned Mount St. Helens into a wasteland. Gone was the symmetrical Fuji-like cone and replacing it was a gaping maw of a horseshoe-shaped crater two miles long by a mile and a half wide, and over 2,000 feet deep with an opening to the north. Spirit Lake was forever changed. Its new elevation was 270 feet higher than the former shoreline, with the new lake bed being raised to a height more than its former surface. This was due to an immense landslide deposit, caused by an 5.1 magnitude earthquake-preceded collapse of Mount St. Helens' north flank in the first few terrifying moments of the 1980 eruption.
Through publicly available data, I have been able to recreate this experience in FSX.
Here's what is featured:
Mount St. Helens' pre-1980 terrain mesh. (30m mesh - the only resolution available)
Mount St. Helens 1-meter resolution aerial imagery from 1972 (for the peak itself; Includes seasonal variations)
Harry Truman's Mount St. Helens Lodge
Spirit Lake USFS Ranger Station
Spirit Lake Lodge (downstream from the Mount St. Helens Lodge by two miles)
Harmony Falls Lodge (In Progress)
YMCA Spirit Lake Camp (In Progress)
Complete realignment of Highway 504 to its pre-1980 alignment, courtesy 1975 USGS Topo data.
Complete realignment of Spirit Lake's shoreline to pre-1980 contour data.
Hundreds of miles of pre-1980 logging roads
Complete landclass reassignment including pre-1980 logging clearcuts and reshaping the debris flow area to a lush forested valley.
And more!
