Product · Diorite 1.0
One system.
Four instruments.
The Conditions Engine, Field Mode, Gear Planner and Pace Model share one understanding of you, your partners and your objective. Plan on the laptop, carry it on the phone, glance at it on the wrist.
Day 2 · Summit push
Upper Exum Ridge
Elevation
12,300 ft · 1,475 ft to summit
Built like gear.
Each piece earns its weight.
Every module works on its own. Together they make the kind of partner who has already read everything and still asks what time you want to be back at the car.
Hour-by-hour hazard, not a sun icon.
The Conditions Engine blends five weather models, the avalanche bulletin, station observations and recent trip reports into a single hazard timeline for your exact route, then finds the window.
- aModel disagreement shown, not hidden, with a reason for the weighting
- bElevation and aspect specific: the ridge gets its own forecast, not the town
- cRe-briefs automatically when a new model run changes the answer
Hazard timeline · Sat
Window 05:00 to 11:40Full reasoning with zero bars.
A compact model runs entirely on your phone. Navigation, whiteout route-finding, bail-route planning and turnaround math keep working in the deepest canyon.
- aWhiteout guidance with bearing and distance back to the line
- bRe-routes around closures, rockfall or weather using downloaded terrain
- cQueues check-ins and sends them via satellite messenger or next signal
You are 40 m east of the descent line. To get back on route:
Bearing 214°, 60 m to rejoin
Cairns resume at 3,050 m
Regroup at the saddle boulder
Then take the Garnet Canyon trail: 2.1 mi, mostly downhill. Visibility improves below 2,900 m. At your current pace, trailhead by 13:20.
The rack, split. The forgotten thing, flagged.
Tell Diorite what you own once. For each trip it builds a pack list from the route and forecast, splits shared gear across the party, and explains every addition.
- aGear closet with weights, ages and retirement reminders for soft goods
- bPer-pitch rack suggestions from topo data
- cExplains why: "Axe added: snow reported in the descent gully on 11 June"

- cLoad-aware for multi-day trips and back-to-back objectives
