Why it is an analog
Historic comparison site for volcanic vs impact crater origin; good terrain scores.
Key differences: where the analogy breaks down
Volcanic origin; eroded; desert grassland.
Experiments done
USGS Astrogeology (Shoemaker era) mapped maar-diatremes here and compared them with lunar craters, helping set criteria to separate volcanic from impact origins.
Experiments proposed
Crater-origin discrimination training (maar vs impact) for lunar geologists; diatreme stratigraphy; rover descent into eroded crater walls.
How to adjust it
Simulant patches on maar floors; boulder seeding to lunar rock-abundance statistics.

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
No. The nearest v1 site, "sf volcanic field", is about 122.9 km away.
| Score view | Result | Percentile | Score | Distance to tile (km) | Overlap flag |
|---|---|---|---|---|---|
| Connecting Ridge C1, Base | Scored | 89.5 | 15.3 | 9.2 | Not in a flagged tile |
| Connecting Ridge C1, Landing and mobility | Scored | 95.3 | 17.5 | 9.2 | Not in a flagged tile |
| Connecting Ridge C1, Power and night | Scored | 89.5 | 11.1 | 9.2 | Not in a flagged tile |
| Shackleton rim, Base | Scored | 91.0 | 37.0 | 18.4 | Not in a flagged tile |
| Shackleton rim, Landing and mobility | Scored | 98.5 | 42.3 | 18.4 | In a flagged tile |
| Shackleton rim, Power and night | Scored | 91.0 | 26.9 | 18.4 | Not 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.
