AvyEyes is a graphical database of avalanches.

By default, AvyEyes displays all avalanches within the geographic bounds of the current view. To view avalanches in a different area, pan or zoom the view to that location. Click the ? button in the upper right hand corner for help using the 3D Cesium view with the mouse or touch gestures.

Avalanches can be further filtered by date, SWAG classification, and how many people were caught or killed in the slide. Use the controls on the left to filter the returned avalanches by any of those criteria.

Once the view is zoomed to within 10,000 meters of a given avalanche (either by clicking on an avalanche pin or zooming in manually), the pin marking that avalanche is replaced by the avalanche path. Click on the red path for the avalanche details and images of the slide.


Filter Fields

Dates: Only avalanches that occurred within the bounding dates (inclusive of the from and to dates) will be returned. Leaving the from date blank will return avalanches back to Jan. 1 1970; leaving the to date blank will return avalanches up to today.

Type, Trigger, and Interface: If specified, only avalanches with the exact type, trigger, or interface SWAG codes will be returned. Leaving any of these fields blank will return avalanches with any SWAG classification.

R/D size: If specified, only avalanches with an R/D size greater than or equal to the specified value will be returned. Leaving R/D size blank will return avalanches of any size.

Caught and Killed Human Numbers: If specified, only avalanches that caught or killed greater than or equal to the specified number of humans will be returned. Leaving either field empty will return avalanches that caught or killed any number of humans (including those that did not catch/kill any humans).

Each of the eight search fields may be independently specified or left blank. If multiple fields are specified, they are combined with a boolean AND to produce the aggregate search criteria.


Examples

Example 1: A from date of 12/1/2005 is entered along with an R size of 2. All other fields are left blank.
Result: Only avalanches that occurred within the geographic bounds of the current map view on or after December 1, 2005 with an R size greater than or equal to 2 will be displayed.

Example 2: A from date of 11/25/2008, a to date of 3/27/2012, a type of HS - Hard Slab Avalanche, a trigger value of AS - Skier and a caught value of 1 are specified. All other fields are left blank.
Result: All hard slab avalanches that occurred within the geographic bounds of the current map view between November 25, 2008 and March 27, 2012 that were skier-triggered and caught at least 1 human will be displayed.

There are two parts to submitting an avalanche report on AvyEyes: 1) drawing the avalanche path on the 3D map and 2) entering the avalanche details.

Drawing the avalanche path:

The primary piece of data in AvyEyes is the avalanche location, so the first part of the report process is to draw the avalanche path on the 3D map with the mouse. AvyEyes guides the report submitter through a 3-step process to draw the avalanche path:

  1. Step 1 is to prime the map by entering a nearby location to the avalanche. AvyEyes will fly to that location and thereby minimize the amount of manual zooming required in step 2.
  2. Step 2 is to zoom/tilt/rotate the 3D map with the mouse to get a close-up view of the exact slope that slid.
  3. Step 3 is trace the avalanche path perimeter with the mouse. One left-click of the mouse starts the trace and a second left-click completes the trace. After the second left-click AvyEyes will ask the report submitter to accept the drawing or choose to redraw if the drawing didnt come out right. Tracing the avalanche path takes a little practice and you can redraw as many times as needed to get the path right. However, once the drawing is accepted it cannot be modified.

Here is a good example of a zoomed-in view and avalanche path drawing:

Entering the avalanche details

Once the avalanche path drawing is accepted, the avalanche detail entry screen will be displayed.

  • Aspect, angle, and elevation are pre-populated based on the drawn avalanche path. The aspect and angle are estimated based on the drawing but are also editable in case the estimated values are off. The elevation is accurate based on the drawing and is not editable.
  • Submitter information: An email address is required for the report submitter in case AvyEyes needs to contact the submitter with questions, and to send notification of report submission. Report submitters are also required to self-assess their avalanche education/experience level.
  • Data fields: Aside from the previously mentioned fields, only an area name and the date of the avalanche are required. However, report submitters are encouraged to enter as much information as is known about the avalanche and attach any available pictures of the avalanche (e.g. pictures of the crown, bed surface, accident scene, snow pit profiles, etc). Please refer to the mouse-over help on any field label for an explanation of that field.
  • Submission & Email: The avalanche report is immediately viewable after submission. Upon successful submission an email is sent to the specified email address providing links for publicly sharing the avalanche report and for editing the report. Avalanche reports may be edited for up to seven (7) days after submission.

What:

AvyEyes is a graphical database of avalanches.

The primary piece of data in AvyEyes is the avalanche location. The avalanche path is drawn on the map by the avalanche report submitter and displayed three-dimensionally to anyone searching for avalanches at a given location. Avalanche reports are also directly sharable/linkable with short URLs or social plugins.

Accuracy Disclaimer: Avalanche paths in AvyEyes are drawn freehand by the report submitter using the mouse. Avalanche paths are NOT derived from GPS coordinates or any other precise form of survey/measurement. Therefore the avalanche paths displayed on AvyEyes can be assumed to contain some degree of inaccuracy resulting from the report submitter misremembering the exact path shape or rendering it inaccurately.

Why:

The driving purpose behind AvyEyes is to enable people to visualize avalanches. By requiring the report submitter to draw the avalanche path on the map, AvyEyes records the geographic location of the avalanche. And by allowing the user to zoom, tilt, rotate, and fly around avalanches in 3D, AvyEyes gives the user a new way to look at avalanches and share avalanche reports.

AvyEyes is intended to be a collaborative and educational tool for the backcountry community. The hope is that AvyEyes will foster communication and knowledge-sharing between both novice and experienced backcountry travelers by showing which slopes have historically produced what types of avalanches.

Step 1

If this is your first AvyEyes report, you may want to read the complete report instructions here.

Begin the report by flying to the general area of the avalanche. This will decrease the amount of manual zooming required in the next step to get the slope in view.

Use the location field below to fly the view to a place near the avalanche. Good locations to use are nearby towns (Silverton CO, Snowbird UT, etc), mountain passes (Vail Pass, Stevens Pass, etc), or well-known mountains (Mt. Elbert, Mt. Rainier, etc).

AvyEyes will attempt to geocode the location and fly to that place.

Step 2

Now use the mouse to zoom, rotate, and tilt the 3D map to get a close-up view of the avalanche path.

Zooming in (mouse wheel or right-click & drag) and tilting/rotating the view (control key + left-click & drag) to look directly at the slope usually provides the best view for drawing. See an example here.

Click the ? question mark button in the upper right hand corner for mouse instructions.

Once you have a close-up view of the entire avalanche path click the button below to start drawing.

Step 3

The mouse is now set to draw. Trace the avalanche path perimeter on the 3D map.

The first left-click (click and release) begins the trace of the avalanche path perimeter.

A second left-click (click and release) completes the perimeter trace.

Are you satisfied with the drawing?

Click "Accept Drawing" to keep the current drawing and continue on to enter the avalanche details.

Click "Redraw" to erase the current drawing and try again.

You can redraw as many times as needed to get it right, but once you accept the drawing it cannot be modified.

    Comments

    Write as much or as little as you want. People may be interested to know the events leading up the avalanche, a description of the snowpack, the weather, the scene/terrain, any human factors involved, the events following the avalanche and/or any rescue effort, etc.

    Tip: Copy & paste text from a local file to avoid accidental data loss

    Images

    • There is a limit of 20 images per avalanche report and each image must be less than 5 MB
    • Once image thumbnails appear use the green pencil to add a caption and the red to delete
    • Order images by dragging them with the move cursor within the drop box
    • Uploading images may take a few minutes...
