Ski Resort Closures and Opportunities for Sustainability in North America
Bibliographic record
Abstract
More than half of the ski resorts in North America have closed since the early building booms—many facing a warming climate and pressures to find water to make artificial snow. Researching and documenting all resorts between 1969–2019, we find that 59% of all resorts in North America have closed since the resort boom of the 1960s and 70s (65% in the United States, 31% in Canada). This shift has left some states or provinces with only one or no resorts remaining. To proactively persevere with a variable climate, less water, and a need for more energy to make snow, we suggest mountains holistically plan for sustainability. Recommendations include third party environmental certification, commitment to sustainability at the management level, communication to customers about sustainability practices and implementing unique models for remaining open and competitive. These practices include resort consolidation, multi-mountain passes, and/or unique ownership models. We believe that ski resorts must focus on positive environmental practices, sustainability planning, and climate change adaptation if they want to remain viable and competitive in the coming decades.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
