Viewshed of the entire #PacificCrestTrail. A viewshed is the unobstructed area you can see standing at a given location. A vista, you probably have expansive views. The bottom of a canyon, maybe not so much. www.youtube.com/watch?v=tmY2... There's one for the #JohnMuirTrail, too! #ParkChat

How cold does it get? Probably the most frequent question asked by hikers. Fortunately, it's easy to answer empirically using climate data. Entire year graph and July min temp overlay for visible trail. www.postholer.com/map/Pacific-... #PacificCrestTrail #JohnMuirTrail #ParkChat

It looks like each hex has the min value in each hex polygon, then the hex and Z values are all exaggerated by some postive N value. Either way, it's damn cool!

Hiking the Pacific Crest Trail that runs through three western states is already challenging. Now the grueling journey may become even tougher this year due to federal cuts.

Just a heads up. If you're looking to hike in NorCal between Castella and Seiad Valley (this includes Etna), snow conditions are ~200% of normal. Often, you can get in there late May/early June. Check before you go! www.postholer.com/snow/Pacific...

April 1st, 2025 has arrived! Highlights: + Sierra, 106% of average or near normal. + Central OR, 280% average, snowiest in at least 22 years! + Northern Cascades WA, tad below normal. www.postholer.com/snow/Pacific... Depending on melt, hikers in the 3 Sisters OR area might see snow into August.

Losing a shoe. Having a deer walk off with a salty and tasty trail runner or two. I'm freaky about keeping my shoes tied down or in my tent if not cowboy camping.

#PCT in Washington, 7 trail miles south of Cispus Pass. 2:00AM or so, was awoken by a loud, thunderous noise my groggy head couldn't wrap around. Dirt, duff flying all over me. Something spooked a herd of about 70 elk. Nearly, got trampled. Dozens of bear encounters in life, but this! #ParkChat

Sierra 'trail snow' is now 116% of average for this date, thanks to the recent, significant system. San Jacinto, Big Bear and the Angeles NF in SoCal also received a good dump. www.postholer.com/snow/Pacific...

Ladies & gentleman, it snowed. The sierra got a significant bump over the last few days, going from 60% to 90% trail snow, SWE. www.postholer.com/snow/Pacific... Still 2 months to go till peak sierra snow season, so stay tuned! #PacificCrestTrail #JohnMuirTrail

Pacific Crest Trail @pacificcresttrail.bsky.social · 30/01/2025

Rainfall (not SWE) across the sierra is continuing to look very dry, ranging from 30%-70% of normal, around 50% overall. Plenty of winter remains to turn that around. Let's wait and see how it plays out. Good for hikers, maybe dry water sources in the south. www.postholer.com/map/Pacific-...

Pacific Crest Trail @pacificcresttrail.bsky.social · 22/01/2025

As of Jan 22 the first 500 miles is between 2% and 20% of normal. Some areas are 5-10 inches below normal! That's huge for socal.

Pacific Crest Trail @pacificcresttrail.bsky.social · 22/01/2025

Here's the latest 'trail snow' conditions in the sierra. The very, very dry stretch continues. Trail snow between Crabtree Mdw & Tuolumne Mdw is at 66% of normal for this time of year. Let's see what the rest of winter holds: www.postholer.com/snow/Pacific... #PacificCrestTrail #JohnMuirTrail

Pacific Crest Trail @pacificcresttrail.bsky.social · 10/01/2025

Looking at the first 100 miles. If you start in March, climate says you're looking at up to 4 inches of rain and min temps around 30. The chart below says nothing of wind. I'm not trying to rain on your hike. ;) www.postholer.com/map/Pacific-...

Pacific Crest Trail @pacificcresttrail.bsky.social · 09/01/2025

How dry is the southern California #PCT? The first 500 miles of trail is currently 5% to 25% of normal. This translates roughly 5-10 inches of rain so far, with mountain areas at the 25% end. See how this water year compares to climate, anywhere along the trail. www.postholer.com/map/Pacific-...

Pacific Crest Trail @pacificcresttrail.bsky.social · 07/01/2025

Sierra trail snow is at %85 of normal. Oregon trail snow is over 200%, easily exceeding Apr 1! Northern Washington, north of Glacier Peak, is very average, with southern & central well above average. So far, looking good for north-bounders! Still early, though. www.postholer.com/snow/Pacific...

That's always been one of the most revered places for me, in that area. You've slogged down San Jacinto, through very dry trail and finally reach substantial water just beyond Red Dome. It's a real treat! 3 times for me and I remember each. Thanks for the photo and mental nudge!

Depends on the trail. In the U.S. bikes are not allowed on national scenic trails, even if you carry it. So, if you consider the PCT, CDT & AT that's over 7,000 miles of trail without bikes. Otherwise, I would put my pack on the bike and push it, make the bike earn its keep!
