Mount St. Helens officials are selling climbing permits for the upcoming season.

The Columbian ( http://is.gd/ONjCzu) reports permits are required to go above 4,800 feet on the volcano. During the peak season - between April 1 and Oct. 31 - a fee of $22 is charged for each permit.

There is no charge between Nov. 1 and March 31.

Permits are sold on a first-come, first-served basis. The U.S. Forest Service says that from May 15 until the end of October, officials impose a limit of 100 permits per day to minimize impact on the mountain's natural regeneration.

Peak season climbing permits can be purchased online through the Mount St. Helens Institute.
