Fifes Peaks are located east of the Cascade crest. Most weather fronts originating in the Pacific Ocean travel northeast toward the Cascade Mountains.As fronts approach, they are forced upward by the peaks of the Cascade Range (orographic lift), causing them to drop their moisture in the form of rain or snow onto the Cascades.
Cascade Volcanic Arc Pemberton Volcanic Belt Mount Overill is a volcanic peak in southwestern British Columbia , Canada , located 81 km (50 mi) east of Rivers Inlet and 2 km (1 mi) northwest of Mount Somolenko .
The active stratovolcano of Mount St. Helens is located only 19 miles (31 km) to the north-northeast, easily visible from the summit of Tumtum Mountain on clear days. The historic Yale Bridge , a one-lane metal suspension bridge built in 1932 over the steep canyon of the Lewis River at the eastern end of Lake Merwin , is located about 2.5 miles ...

The human population within 6.2 miles (10 km) of West Crater is slightly more than 500 people, but more than 14,000 people live within 19 miles (30 km) of the volcano, and more than 2 million live within 62 miles (100 km). [2] However, the United States Geological Survey lists the threat potential from West Crater as "Low/Very Low". [21]
Mount Scott first erupted about 420,000 years ago and is one of the oldest volcanoes in the Mount Mazama complex. [8] [9] It erupted mainly andesitic lavas before becoming extinct in the late Pleistocene. [10] Since it was relatively far away from the main flanks of Mount Mazama, it survived the mountain's massive explosion that occurred around ...
The Cascade volcanoes are part of the Pacific Ring of Fire that includes over 160 active volcanoes. Articles listed under this category should be cross-listed under the correct geographical categories too. For mountain range categories, the appropriate choices are Category:Cascade Range or Category:Pacific Ranges.
The Cascade volcanoes have had more than 100 eruptions over the past few thousand years, many of them explosive eruptions. [21] However, certain Cascade volcanoes can be dormant for hundreds or thousands of years between eruptions, and therefore the great risk caused by volcanic activity in the regions is not always readily apparent.
