See which runs are actually harder or easier than their trail signs suggest —
scored using real terrain data, not just resort ratings.
Adjust to your skiing style
Use the scoring sliders to weight what matters to you — short steep pitches (max slope), sustained steepness (avg slope), or altitude exposure (elevation).
Ratings are relative to each resort
A Black Diamond at Camelback (PA) is very different from one at Jackson Hole (WY). Computed ratings match each resort's own official distribution, so you're always comparing runs within the same mountain.
Reading the Verdict column
Overestimated — rated harder than terrain suggests.
Underestimated — tougher than the rating implies.
Accurate — they match.
