Every backcountry trip starts with the same ritual: Avalanche Canada for the forecast, SpotWx for weather models, Windy for wind, CalTopo for terrain, DriveBC for road conditions. Five apps, five logins, five data formats. The most critical step -- combining what the forecast says with what the terrain actually looks like -- happens entirely in your head.
Backcountry Aspect puts it all on one map. Drop a pin anywhere in BC, and you get slope angle, aspect, ATES classification, danger rating, weather, wind history, station data, and field observations -- all contextualized to that specific slope and elevation band.
Search or browse anywhere in BC. Tap to place a pin on the slope you want to assess.
Slope angle at 1m resolution, aspect, ATES rating, elevation band, and the current avalanche bulletin -- all at your pin.
Brian analyzes your specific slope against the day's danger, weather, and snowpack data. Not a bulletin summary -- a targeted field assessment.
Full-map slope angle, aspect shading, hazard-terrain intersection, elevation bands, and ATES zones. Not locked behind a paywall. Every terrain overlay, free.
154 weather stations, 24-hour wind history for wind slab assessment, live DriveBC road conditions, and recent MIN field observations.
Route drawing with terrain stats, GPS recording, built-in inclinometer, and 10 saved locations. Plan your line and see slope distribution along the way.
Dynamic wind loading overlay, precipitation phase, snow accumulation, satellite imagery with history timeline, snowpack timeline, and 10-day extended forecast.
Brian synthesizes terrain, forecast, weather, and snowpack into a targeted field assessment for your specific slope. 1 free/month, 10 on Premium.
Solar exposure overlay with time scrubber, PRA (potential release areas), 1m LiDAR terrain, observation recording, and programmatic API access.
