"Starting today those looking to climb on Mt. Rainier will be charged an annual climbing permit fee of 43 dollars for the privilege of venturing onto the mountain's glaciers or traveling above 10,000 feet. This is a 13-dollar increase from the previous 30-dollar climbing permit. Youth (under age 25) will only be charged 30 dollars for a Youth Climbing Permit.
This permit will be valid for the calendar year in which it was purchased, with November and December permits being valid for the following year. The Park Service blames rising costs in their mountaineering program for the fee increase. The specific sources of these increased costs include the whole permit infrastructure, weather monitoring, maintaining rangers on the mountain as well as environmental clean up and monitoring."
Still 30 bucks fer young folk like me though...
