The Mount St. Helens Institute is relaunching its climbing permit system nearly four weeks after rampant demand crippled this season’s first online sales event.

Starting at 9 a.m. Monday, those hoping to climb the famous volcano will have another chance to buy a 2018 climbing permit. The permits are available from April 1 to Oct. 31, at a cost of $22 per climber, at the Institute’s website.

“There was definitely a lesson learned last time — I don’t think one we could have predicted, but it gave us an idea of the real scale of demand out there,” said Ray Yurkewycz, the Institute’s executive director. “We’ve gone with a company that can handle this scale.”

Yurkewycz said 4,000 to 5,000 people visited the Institute’s website to purchase climbing permits in the first hour last year. This year, 15,000 to 17,000 people visited in the first hour.

For the latest round of sales, the Mount St. Helens Institute has contracted services from a new transaction processor in hopes of avoiding the lengthy delays consumers experienced when they tried to buy tickets on Feb. 1, when tickets initially went on sale.
