Why it is an analog
Historic first astronaut training site (low physical similarity).
Key differences: where the analogy breaks down
Sedimentary rocks unlike the Moon; extreme relief; vegetation and water.
Experiments done
First NASA astronaut geology field trip (March 1964): reading stratigraphy and recording field observations, the foundation for later lunar field geology.
Experiments proposed
Stratigraphic-reading training for crater-wall and rille exposures; long-baseline stereo mapping.
How to adjust it
Little to gain physically; use as classroom for stratigraphy only.

v1 score, percentile and overlap flag
A descriptive lookup of scores v1 already stored. It is not a test, and a high percentile here does not show that this is a good analog.
v1 used this site
Unknown. The nearest v1 site, "sf volcanic field", is about 99.9 km away, and the files cannot say whether v1 meant the same place.
| Score view | Result | Percentile | Score | Distance to tile (km) | Overlap flag |
|---|---|---|---|---|---|
| Connecting Ridge C1, Base | Scored | 96.1 | 34.9 | 10.8 | Not in a flagged tile |
| Connecting Ridge C1, Landing and mobility | Missing datano tile in range passed; some tiles lack data | not provided | not provided | not provided | not provided |
| Connecting Ridge C1, Power and night | Scored | 96.1 | 25.4 | 10.8 | Not in a flagged tile |
| Shackleton rim, Base | Scored | 99.2 | 55.5 | 15.1 | In a flagged tile |
| Shackleton rim, Landing and mobility | Missing datano tile in range passed; some tiles lack data | not provided | not provided | not provided | not provided |
| Shackleton rim, Power and night | Scored | 99.2 | 40.3 | 15.1 | In a flagged tile |
Overlap flag: whether the tile used for the score is one v1 flagged as stable in its top group across the Monte Carlo runs.
What these scores can and cannot tell you
- This is a lookup of scores v1 already stored. It is descriptive and is not a test of the method.
- A site is matched to the best-scoring tile that passed the gates within the match radius. A different radius would give different numbers.
- Tiles are large compared with most sites, so a score describes the surrounding area, not the site itself.
- Scores exist only for tiles that passed the land-cover and data gates. A gated-out or unscored site has no score, which says nothing about how good an analog it is.
- Percentile is the share of scored tiles in that view with a lower score.
- The Moon score is effectively terrain only. Mars is a low-confidence secondary result.
- v1 failed its negative controls, so a high percentile here does not show that a site is a good analog.
- The ranking is not checked against independent data. Gravity, air, dust and radiation are not scored.
- Sites are compared with views of their own body only.
- Match radius: 20 km, the radius v1 used.
