Scott you're probably working off the old like (with the 'home.nps' domain). Here are the links I have:
Trail Status Link.
With each area having their own webpage, starting with
https://www.nps.gov/applications/glac/t ... tus.cfm?t= and adding the abbreviation BR=Belly River, MG = Many Glacier, TM = Two Medicine, etc).
As Blanka noted, the trail status page now has an interactive map - pretty cool - I tried to make something similar 2 years ago. It nicely captures the 'closed' sections, but misses 'winter status' and the details (bridge status, wildlife observations, planned clearance date, etc) found on the trail status pages, such that there is more 'closed' than what is on the map. Now I saw 'closed' in air quotes because as I understand it, not clear does not equal closed, such that trails with snow pack and hazards can be 'open'. I had a near miss 10 years ago on Piegan just 'opening' the day prior albeit with still a 'snow hazard, ice axe/spikes recommended' - whether they would have allowed the permit if that wasn't the case who knows, but often the 'hazards' can be navigated around or carefully through.
Advanced Availability Map Link
Each site has an abbreviation and it's own calendar link, by adding the abbreviation to
https://www.nps.gov/applications/glac/b ... us.cfm?cg= . For instance Granite Park is GRN, Fifty Mountain FIF, etc.
Walk-in availability link
This hasn't worked all year.
Based on my observations, when one is down they are all down. Caveats being that Advanced Reservation Availability was intentionally down during permit processing and Walk-in never being up this year. It's mindboggling to me this is possible in 2022 and question the lack of accountability for maintaining a government website to even the most basic standards. It worked fine in years past, so something is amiss.
