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.

Denny Mountain is one of the better known mineral collecting localities in Washington state, containing a wide variety of attractive skarn minerals. It is the site of the original Denny Claims which followed the contact mineralization. Originally located by Artur Denny (one of the founders of Seattle) in 1869, it was the first recorded lode in the Snoqualmie Pass area. Most of the early work there was in search of economic quantities of Iron. The grade found was fairly high in places, but the impurities in the magnetite and hematite made it useless. Some chalcopyrite was also found but the quantity was insignificant for mining.
- Observable universe (Wikipedia)
The observable universe is a ball-shaped region of the universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time; the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion. Initially, it was estimated that there may be 2 trillion galaxies in the observable universe. That number was reduced in 2021 to only several hundred billion based on data from New Horizons. Assuming the universe is isotropic, the distance to the edge of the observable universe is roughly the same in every direction. That is, the observable universe is a spherical region centered on the observer. Every location in the universe has its own observable universe, which may or may not overlap with the one centered on Earth.
