Welch Peak is a 2,431-metre (7,976-foot) mountain summit in the Cheam Range , located in southwestern British Columbia , Canada , near Chilliwack . It is the highest summit in the range. The mountain is named after one of the partners in the engineering firm Foley, Welch and Stewart who built and operated the Lucky Four Mine located near the peak. Nearby peaks are also named after the other partners ( Foley Peak and Stewart Peak ).
6-680: Welch Peak is related to the Chilliwack batholith , which intruded the region 26 to 29 million years ago after the major orogenic episodes in the region. This is part of the Pemberton Volcanic Belt , an eroded volcanic belt that formed as a result of subduction of the Farallon Plate starting 29 million years ago. During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured
12-619: Is part of the Pemberton Volcanic Belt and is the largest mass of exposed intrusive rock in the Cascade Volcanic Arc . The age of the Chilliwack batholith ranges from 26 to 29 million years old. 49°01′N 121°35′W / 49.017°N 121.583°W / 49.017; -121.583 This article about a location on the Coast of British Columbia , Canada is a stub .

18-516: The Cascade Range where they are forced upward by the range ( Orographic lift ), causing them to drop their moisture in the form of rain or snowfall. As a result, the Cascade Mountains experience high precipitation, especially during the winter months in the form of snowfall. Temperatures can drop below −20 °C with wind chill factors below −30 °C. The months July through September offer
24-563: The diverse topography and drastic elevation changes over the Cascade Range leading to various climate differences which lead to vegetation variety defining the ecoregions in this area. Based on the Köppen climate classification , Welch Peak is located in the marine west coast climate zone of western North America . Most weather fronts originate in the Pacific Ocean , and travel east toward
30-570: The landscape leaving deposits of rock debris. The U-shaped cross section of the river valleys is a result of recent glaciation. Uplift and faulting in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the North Cascades area. The North Cascades features some of the most rugged topography in the Cascade Range with craggy peaks and ridges, deep glacial valleys , and granite spires. Geological events occurring many years ago created
36-618: The most favorable weather for climbing Welch Peak. Chilliwack batholith The Chilliwack Batholith is a large batholith that forms much of the North Cascades in southwestern British Columbia , Canada and the U.S. state of Washington . The geological structure is named after the Chilliwack River Valley, where it outcrops in many places. It does not outcrop anywhere near the City of Chilliwack . The Chilliwack Batholith
