6116 - Pinnacle points


"An interactive map of Earth's Pinnacle Points (points from which no higher point can be seen.)"

An interesting map of the highest points around the globe. Here is what the interactive map looks like.


Here is a link to the actual map. I've got nothing around me. The closest point is in Arkansas.


I don't know how this will work out on a cell phone.  I hope it does.


Here's a Reddit post from the guy that is doing this project...

JamesonLKJ OP

The site is not best used on mobile, but it's good enough for now.

Differences since I last posted:

  • I now take topography into account when determining if 2 points can see each other. Before, I was doing a weird approximation using prominence. This result is MUCH more accurate. Refer to the info section of the site if you want to know more about the algorithm.

  • I now only include pinnacle points with a prominence greater than 100 m. Before, the cut off was 30 m.

  • You can choose what style of map to display

Future Improvements:

  • I've been looking at this result for way too long and there are some minor inaccuracies I noticed. The 2 highest pinnacle points on the island of New Guinea for example. Both are VERY close to peaks with slightly higher elevation. I think I have a way to fix these minor inaccuracies that pop up. Stay tuned.

  5. Looks like we need to head over to Mt. Shasta. Thanks for sharing, Mike. This is really cool.

  6. Cloudia - Time to do some mountain climbing?

    Bill - Not many high points in the political realm.

    Deb - Any Pinnacle Points around you? Or are you in that middle waste land like I am?

    Matt - It's only 14,179 ft. Just a nice afternoons walk, right?

  7. Interesting, but you already answered my question about where the closest one is for me.

  8. Interesting to me only in the fact that there are people who spend hours doing this "research" while I'm drooling in the corner.

  9. It doesn't explain the significance of the different colours. Are the red ones volcanos? Are the green ones higher than the rest? Why are some yellow?

  10. Kathy - There's not much close to us.

    Peg - Are you drooling out of jealousy? No?

    River - The colors are elevation. Click on the down arrow in the upper right-hand corner.
    Green Elevation < 2000 m
    Yellow 2000 m ≤ Elevation < 4000 m
    Orange 4000 m ≤ Elevation < 6000 m
    Red Elevation ≥ 6000 m

  11. What possible use are these data?

  12. Anon - You'll have to ask the people who use them.
