Why it is an analog
It combines a large impact crater with high-altitude cold-dry ground, so it scores better on GSOP's cold-dry and temperature terms than any lowland crater. It has no analog history, and the nearest known site (Ladakh) is about 750 km away.
Key differences: where the analogy breaks down
Metasedimentary/granitic target; lake; pasture use; impact origin still debated.
Experiments done
Identified from space imagery (c. 1987); field studies 1987-91 (Gurov et al.) and 2011 (Bouley et al.) on breccias, shocked minerals and the impact-vs-rift debate.
Experiments proposed
Large complex-crater geology at ~4,000 m: low air pressure (~0.6 atm), cold permafrost ground and strong UV in one place; central-uplift traverses; rover cold-start and battery tests; low-pressure dust experiments.
How to adjust it
Simulant pads on rim terraces; shade fences for cold plots.

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, "ladakh puga", is about 777.3 km away.
| Score view | Result | Percentile | Score | Distance to tile (km) | Overlap flag |
|---|---|---|---|---|---|
| Connecting Ridge C1, Base | Scored | 98.7 | 44.4 | 19.5 | Not in a flagged tile |
| Connecting Ridge C1, Landing and mobility | Scored | 99.6 | 44.8 | 19.9 | In a flagged tile |
| Connecting Ridge C1, Power and night | Scored | 98.7 | 32.3 | 19.5 | Not in a flagged tile |
| Shackleton rim, Base | Scored | 96.4 | 48.7 | 17.4 | Not in a flagged tile |
| Shackleton rim, Landing and mobility | Scored | 99.8 | 52.0 | 16.0 | In a flagged tile |
| Shackleton rim, Power and night | Scored | 96.4 | 35.4 | 17.4 | 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.
