Like the arteries that supply blood to the heart -- the coronary arteries -- the carotid arteries can also develop atherosclerosis or âhardening of the arteriesâ on the inside of the vessels. Over time, the buildup of fatty substances and cholesterol narrows the carotid arteries.
NPS/Steve Redman. Weather patterns at Mount Rainier are strongly influenced by the Pacific Ocean, elevation, and latitude. The climate is generally cool and rainy, with summer highs in the 60s and 70s. While July and August are the sunniest months of the year, rain is possible any day, and very likely in spring, fall, and winter.
This part of Mount Rainier National Park receives consistently high amounts of rainfall so the climate and plant communities found here resemble that of a temperate rainforest. The Carbon River road was washed out by the 2006 flood and is open to vehicles only to the Carbon River Ranger Station at the park boundary.
