Denny Mountain (summitpost.org) 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 (mindat.org) 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.

The Scotia Plate and the South Sandwich Plate: Southern Tectonic Dynamics (lacgeo.com) The Scotia Plate and the South Sandwich Plate are pivotal in molding the tectonic features of the southern extents of the South Atlantic and Southern Oceans encircling Antarctica. These plates are essential elements of the complex tectonic mosaic that influences the Southern Hemisphere’s dynamics.
