Over the Thanksgiving vacation, a brand new avalanche security app launched with an purpose to assist backcountry vacationers make higher selections based mostly on higher knowledge. AspectAvy makes use of historic avalanche accident knowledge, the present avalanche forecast, and slope angle to boil backcountry decision-making right down to a easy “go” or “no-go”.
It’s no secret that folks aren’t excellent on the subject of staying out of avalanche-prone areas and annually there are backcountry recreation avalanche deaths (many involving skilled backcountry vacationers) that drive the purpose residence. Nonetheless, AspectAvy sees reassurance within the statistics and says its app would’ve really helpful in opposition to journey in 100% of eventualities pulled from a couple of decade of historic avalanche accidents they ran by their algorithm.
In constructing AspectAvy, we checked out knowledge nobody had earlier than,” mentioned Jeff Banks, Licensed IFMGA information and Co-Founding father of AspectAvy mentioned by way of a press launch in regards to the launch. “We analyzed it fully in another way, and got here to radically totally different conclusions about find out how to maintain skiers protected in avalanche terrain. Like most of us who journey within the backcountry, I’ve misplaced quite a few mates and colleagues to avalanches, and it’s clear that the present avalanche security choices simply aren’t reducing it. We’re excited to share AspectAvy with the backcountry neighborhood, with a mission of saving lives.”Observe: We examined a really a lot beta model of the app final spring in Crested Butte, however have but to check the publicly out there app. We are going to share our ideas as soon as we’ve been capable of area take a look at it completely.
The way it Works
Present avalanche forecasts from state organizations current avalanche situations to the backcountry traveler, however the bulk of the interpretation of what meaning for sensible terrain alternative falls to the consumer. For instance, the Colorado Avalanche Data Heart offers detailed statewide stories every day throughout the season and break down their forecasts and hazard rankings by area. Inside these regional forecasts, there’s then hazard highlighted for sure features (i.e. Northeast-facing slopes above treeline) and narrative forecasts that supply shade across the data (i.e. “keep on with slopes lower than 30 levels”).
From there, it’s as much as the backcountry traveler to interpret the knowledge because it applies to their meant ski zone by combining maps and area observations with their studying of the forecast. This interpretation section is usually the place issues go mistaken and anybody who’s taken avalanche schooling programs has heard in regards to the “human elements” to be careful for. I’ve additionally heard many skilled guides use unofficial phrases like “scary average” or “comfortable average” so as to add nuance to the official avalanche stories of Reasonable Hazard, indicating that there’s experience and steerage not captured within the score scales alone.

AspectAvy goals to mitigate these ambiguities with their extra simple steerage. Their maps present slope angle shading just like what’s out there in OnX Backcountry and CalTopo, however the legend on the high of the app has solely two colours– orange for “Use Warning” and purple for “No-Go” together with slope angle ranges for every. As a result of the bi-color shading is overlaid on the map, it’s simple to search for harmful zones to keep away from on your ascent and descent.
Banks emphasised in an interview with WildSnow that AspectAvy isn’t one other mapping app. He says slope-angle shaded maps from different apps are “the identical colours in June as they’re in January, nevertheless it doesn’t let you know the danger for at this time’s real-time avalanche forecast. It’s like utilizing your blue area ebook. It’s all drawback and no resolution.” AspectAvy’s resolution is highlighting the hazard zones that replicate the present avalanche situations so you possibly can keep away from them and ski lower-risk terrain.
AspectAvy additionally makes use of extra exact LiDAR mapping that captures better nuance in slope angle than conventional USGS maps. Avalanche professionals know that older maps can conceal small pockets of hazard. Banks says that AspectAvy at present covers the decrease 48 states wherever they can mix forecast knowledge and LiDAR maps and he expects to have LiDAR-grade basemaps for 100% of the forecasted terrain by January 1, 2024.
Additionally they have a voluntary “Confirm the Forecast” guidelines pop-up within the app that not solely offers a structured course of for customers to cease and examine what the app is telling them with situations on the bottom, but additionally shares the info with the app and adjusts suggestions in real-time for that consumer. I’m curious to see how this function performs out as extra customers be a part of the platform and submit area stories by way of the app. For now, area observations solely have an effect on that consumer’s app, however Banks sees potentialities of utilizing user-reported commentary knowledge for real-time updates just like how Waze warns drivers of accidents and pace traps.
Subject Testing
Banks informed us that widespread testing of the AspectAvy app by the general public will give their crew priceless suggestions to evolve the app shortly. “As a backcountry neighborhood, everyone knows somebody who has died in an avalanche. We’re asking the neighborhood to assist resolve our shared avalanche drawback. Ship us your suggestions so we will make it higher.”
In case you’re getting out touring, are within the decrease 48, and have a iPhone, we encourage you to obtain the app and use their 30-day free trial. You’ll must have an account with the App Retailer to obtain, however received’t be charged the $49.99 annual payment in case you cancel inside 30 days. (The app is iPhone-only for the foreseeable future. Banks says the extra difficult growth related to Android apps isn’t possible whereas within the startup section.)
Have you ever used AspectAvy? Share your suggestions and questions within the feedback and we’ll get solutions and share them after we replace this text with area testing of the app.

He had no backcountry gear, discovered Wild Snow, learn up on backcountry snowboarding and purchased some body bindings for a pair of G3 Reverends so he didn’t have to purchase touring boots. He moved to Breckenridge, CO a yr later and at this time he skis 100+ days a yr, most of them backcountry.
