A Humid Place on the Moon — 2 Comments

  1. So many of the posts here on Sacred Space Astronomy will lead me to wander off onto places on the web, spending time looking into one or another thing mentioned in their texts. And your posts, Rik, are no different. In your case, I’m often led to the LROC Quick Map site you noted, zooming in and scrolling around its lunar imagery of one or another feature you’ve mentioned. After reading your post this morning, I found something there, today, that I thought I’d share with your other readers who might be interested.

    Here’s a link to Gassendi crater on LROC Quick Map: If I’ve centered it correctly, if you keep clicking the plus (“+”) button in the upper right corner, eventually (about 8 clicks in), you should zoom all the way down to the lunar surface where you will find two boulders that have left a very clear trail behind them where they tumbled down from higher up on Gassendi’s central peak. If I’ve done this wrong, this link should take you to them directly:

    I’m continually amazed that I can just happen upon boulders and boulder tracks on the flanks of mountains on the Moon (and other cool views), just sitting here at my home computer. Being stuck here at home self-isolating, I suspect I could spend all day zooming in on the things with the LROC Quick Map web page.

  2. It seems where that first link centers you depends on the dimensions of your browser window. So if you don’t see boulders and boulder tracks after zooming in, use that second link to find them:

    In fact, if you zoom in another step, you’ll find boulder tracks all over that area. Would those just happen over time normally? Or is it more likely they resulted from a Moon quake or a jolt from a nearby impact? Or something else?
