how does it work?

mountain data

Rime maintains a complete map of every trail on the mountain — name, type, aspect, and elevation. Every hour it reads weather across multiple elevations: temperature, wind, precipitation, and sun exposure.

deterministic conditions scoring

A conditions engine tracks the snow state on every trail over time — building up a picture of how conditions have accumulated, shifted, and decayed. Last week's storm, Tuesday's refreeze, three days of afternoon sun.

detailed mountain plan

Rime gives you a plan built from current trail conditions, the two-day forecast, and embedded local knowledge about the mountain — which runs to ski, which to avoid, and when to be where.

Which runs should I ski today at Copper Mountain?

Overview Consolidated, chalky conditions across the board — grippy and forgiving, but no standout powder. Fresh corduroy is the move today. Take advantage of it before it gets skied off.

Morning Head to Super Bee. Hit Bouncer, Main Vein, or Andy's Encore for fresh + fast corduroy.

Midday Shift to Union Peak. Revenge and Timber Ridge will stay pleasant through midday. Little Trees is a mellow, quiet option if you want to mix it up.

Afternoon Finish in the trees. Timberline and Union Meadows stay consistent well into the afternoon — sheltered, quiet, and forgiving when the open groomers start to feel worn. Conditions are solid and predictable — just not spectacular.

why did you make this?

My family has always been obsessive ski day planners. The kind who are thinking two runs ahead before they've finished the first one — tracking which trails will be in best shape at what time, where the lift lines will form, and when to test new terrain. After decades of planning across various mountains, I'm convinced it's the difference between a good ski day and a great one.

The problem is that this knowledge lives in the heads of people who've skied a mountain dozens of times. If you don't have a local in your group, you're guessing: following the crowd, skiing the same groomer everyone else is on, and leaving by 2pm thinking the mountain was fine. Skiing is expensive and getting there takes real effort — a day that doesn't come together stings more than it should.

I built Rime to be that local. Not to replace the experience of knowing a mountain, but to make that kind of knowledge accessible to anyone who shows up and wants to make the most of their day.
