[ 1 ] The Chopping Block can be seen from the North Cascades National Park Newhalem visitor center, weather permitting.
Pinnacle Peak is located in the marine west coast climate zone of western North America. [4] Most weather fronts originating in the Pacific Ocean move northeast toward the Cascade Mountains . As fronts approach the North Cascades , they are forced upward by the peaks of the Cascade Range ( orographic lift ), causing them to drop their moisture ...
Pinnacle Mountain is composed primarily of granodiorite and hornblende quartz diorite, minerals of the Cardinal Peak pluton.

Although a given calibrated microphone will often have been calibrated by other (secondary) methods, all can be traced (through a process of dissemination) back to a microphone calibrated using the reciprocity method at a National Measurement Institute. Reciprocity calibration is a specialist process, and because it forms the basis of the ...
Well, we used to have a thing called a Decca Tree which was an arrangement where [at] the front edge of an orchestra about 3.2 metres up in the sky you would have a centre microphone roughly in line with the edge of the orchestra, and then maybe 2.5 feet back and 5 feet apart you would have 2 more forming a triangle, omnidirectional microphones.
