Why it is an analog
Most northerly ice-free land (mostly north of 82°N) with only 25-200 mm/yr of precipitation, so it is a true polar desert. Illumination and cold-dry scores rank near the top of the list, and it is far from Haughton and Svalbard. It also gives a northern-hemisphere option to pair with Mount Howe.
Key differences: where the analogy breaks down
Sedimentary rocks; snowfall; no vacuum; summer sun up to ~31°.
Experiments done
Danish Peary Land expeditions (1947-50) built Brønlundhus; archaeology of Independence I/II cultures; Quaternary geology. No planetary analog work.
Experiments proposed
Lunar-polar EVA rehearsal under 24-h low sun (spring/autumn sun stays within a few degrees of the horizon); long-shadow hazard detection; permafrost drilling as an ice-in-regolith analog; pressurised-rover traverses on unvegetated gravel plains; solar-power autonomy under circling sun.
How to adjust it
Simulant pads; shade tents to make permanently shadowed micro-plots; use spring weeks when sun stays below 10°.

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, "haughton", is about 1364.8 km away.
| Score view | Result | Percentile | Score | Distance to tile (km) | Overlap flag |
|---|---|---|---|---|---|
| Connecting Ridge C1, Base | Scored | 98.0 | 41.4 | 12.4 | Not in a flagged tile |
| Connecting Ridge C1, Landing and mobility | Scored | 99.7 | 47.4 | 12.4 | In a flagged tile |
| Connecting Ridge C1, Power and night | Scored | 98.0 | 30.1 | 12.4 | Not in a flagged tile |
| Shackleton rim, Base | Scored | 91.8 | 38.3 | 12.4 | Not in a flagged tile |
| Shackleton rim, Landing and mobility | Scored | 98.9 | 43.8 | 12.4 | Not in a flagged tile |
| Shackleton rim, Power and night | Scored | 91.8 | 27.8 | 12.4 | 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.
