- Denny Mountain is the prominent peak seen to the northwest of Snoqualmie Pass and to the north of I-90. The mountain consists of a one-mile long ridgeline oriented to the NNW with many jagged outcrops. The southern buttress of Denny can be seen towering above I-90 as the road approaches the pass from the west but the actual highpoint of the summit is hidden from eastbound freeway vantage points. The summit can be spotted by westbound drivers from the pass. Its NE face is home to the notoriously challenging Alpental ski area that boasts of having only 3% “easy” slopes and 75% “expert” with 22% in between.
- Manhattan Project (Wikipedia)
The Manhattan Project was a research and development program undertaken during World War II to produce the first nuclear weapons. It was led by the United States in collaboration with the United Kingdom and Canada. From 1942 to 1946, the project was directed by Major General Leslie Groves of the U.S. Army Corps of Engineers. Nuclear physicist J. Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the bombs. The Army program was designated the Manhattan District, as its first headquarters were in Manhattan; the name gradually superseded the official codename, Development of Substitute Materials, for the entire project. The project absorbed its earlier British counterpart, Tube Alloys, and subsumed the program from the American civilian Office of Scientific Research and Development. The Manhattan Project employed nearly 130,000 people at its peak and cost nearly US$2 billion (equivalent to about $27 billion in 2023), over 80 percent of which was for building and operating the plants that produced the fissile material. Research and production took place at more than 30 sites across the US, the UK, and Canada.
