Why it is an analog
Composition is the weakest Earth variable in GSOP (silica index, match-ability 0.4). This is one of the few places with bare, lunar-like anorthosite at high latitude, and it carries a lunar pink-spinel analog that has only just been reported. It is a complement to Mistastin.
Key differences: where the analogy breaks down
Metamorphosed (amphibole-bearing) anorthosite; wet maritime climate.
Experiments done
Rare-earth and trace-element comparisons with lunar anorthosites (1976); pink spinel matching Chandrayaan-1 M3 detections (JpGU 2025).
Experiments proposed
Highland composition ground-truth for orbital spectrometers (M3/LRO); lunar spinel-anorthosite sample-selection training; handheld Raman/LIBS calibration; drilling in plagioclase-rich rock; low-sun Arctic lighting tests.
How to adjust it
Crush local anorthosite into highland simulant on site; cleared test pads.

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, "askja", is about 1644.4 km away.
| Score view | Result | Percentile | Score | Distance to tile (km) | Overlap flag |
|---|---|---|---|---|---|
| Connecting Ridge C1, Base | Scored | 97.8 | 40.9 | 19.9 | Not in a flagged tile |
| Connecting Ridge C1, Landing and mobility | Scored | 99.4 | 41.2 | 15.9 | Not in a flagged tile |
| Connecting Ridge C1, Power and night | Scored | 97.8 | 29.7 | 19.9 | Not in a flagged tile |
| Shackleton rim, Base | Scored | 94.7 | 44.1 | 13.0 | Not in a flagged tile |
| Shackleton rim, Landing and mobility | Scored | 99.8 | 50.5 | 13.0 | Not in a flagged tile |
| Shackleton rim, Power and night | Scored | 94.7 | 32.1 | 13.0 | 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.
