   Yeah, I was on the fence about using an ephemeral link as the HN submission but in the end figured it was the most appealing to this audience. Now that Nathan is done with his effort, he'll be loaning his inReach to Ashly Winchester du

   I put links to the official SPS site on the About page but your point is well taken. The link at the top of the site that says "SPS Peak List" really ought to take you somewhere that you can find out more substantive information t

   Like others have said, it all depends on the ridge. In this case it is the southern half of the Full Palisade Traverse[1] which is a very technical ridge with long sections of 5th class climbing[2]. One way of looking at is that these guys

   I've done this two ways: (1) Tile the world in lat/lng. For each tile, turn it into a NxN grid of lat/lngs within the bounds of the tile. Convert each lat/lng/height (where height comes from your DEM) into ECEF XYZ.

   Thanks! Happy to answer questions. First, about the attribution: there's a small "Attribution" section in the About page, but it's all data I sourced directly from US gov sites. I actively wanted to avoid an attribution

   If you're looking for something worldwide, your best starting point is likely SRTM[1]. If you get into more specific areas you can generally find higher resolution data. Good luck. [1] - https://www2.jpl.nasa.gov/srtm&#

   Assuming everything goes to plan[1] for Nathan's list finish: Today, Wed, July 6: A five-peak, north-to-south traverse of the southern Palisades: Palisade Crest, Norman Clyde, Middle Palisade, Disappointment, and Thumb. Tomorrow, Thurs

   Thank you. While the project is ongoing (probably another month or so), it'll just be for the climbers. But, yes, when they are done I intend to release something that will allow anyone to put their own Strava activities on it. One hug

    Yeah, unfortunately this comes with the territory, especially with this Garmin inReach data. We are running in "expedition mode" which gives us updates about every five minutes but still, you will occasionally get badly spurious p

    I wasn't aware of this -- very cool. Thanks. We have captured a ton of video of the project and they've done a bunch of amazing lines. Hopefully we can put together a few good videos coming out of this.

    Thank you. Unfortunately I have not yet written anything detailed about the renderer. As is typical with this sort of project, I had grand ambitions about many features and articles to write but have really only been able to focus on the da

    Hi HN, I built a website for tracking an attempt by two climbers to set the fastest known time (FKT) on a well-known list of 247 peaks in the Sierra Nevada. While I hope you'll find the whole site interesting[1], the part most likely o
