Hello User, I did not track all of these by any means! I was just able to scrape the internet a bunch and compile what I found. All of these maps will continue to be added to but I tried my best to grab a bunch of info from all sorts of corners of the internet and organize it in one logical space. Thank you to all the unknown people that publicly (knowingly or unknowingly) posted their maps on Caltopo, Powder Project, OnX, Fat Maps, UAC, and assorted trip reports. Make sure to check out the Custom Layering on the right for different terrain modeling options. Also, on the left of all the maps you can alter the current avalanche forecast by creating rules so that the current rose will be displayed on your desired terrain. A note on adding the avalanche forecast. Make sure you are not using the directional degrees that are the option on caltopo. If N facing aspects are affected then you must use the applicable 22.5 degree increment, for N it would be 337.5 - 22.5. DO NOT just use "N" or your information will be incorrect. For degree reference I have listed them below. N: 337.5-22.5 NE:22.5-67.5 E: 67.5-112.5 SE: 112.5-157.5 S: 157.5-202.5 SW: 202.5-247.5 W: 247.5-292.5 NW: 292.5-337.5 If you have any doubts about how to use it then just use the "Avalanche Terrain" layer and figure out the aspect and elevation separately. Additionally, download google earth pro! Export these maps as a KML and then import them into your program. If you need any help my number is 1(315)481-3201 -B
