Best times to check
Every opening our scanner has recorded for this permit (809 of them) by day of week and time of day (Pacific time). An opening is a date that went from closed to open. Dates closing are not counted here, and they make up most of what an availability change is. Darker cells mean more openings landed in that window.

St. Helens drop report questions
How often does St. Helens availability actually move?
Our scanner has recorded 5,974 availability changes for St. Helens since it started tracking, broken down by month above. A change is any shift in the open-date set, so it counts dates closing as well as dates opening. Openings are counted separately, and on a different basis: 809 moments where at least one date went from closed to open. That is what the grid above plots, and it is why the two numbers do not add up to each other.
When is the best time to check for St. Helens cancellations?
The grid above is built from every opening our scanner recorded for St. Helens (dates that went from closed to open), bucketed by day of week and time of day in Pacific time. It's real detection history, a guide to timing your checks.
How fast will I find out if a St. Helens date opens up?
Paid plans are scanned every minute and we tell you within seconds. Free accounts are scanned hourly. Either way, PermitSnag catches the change, so you don't have to refresh the page yourself.
