Cool new app out for your phone called Fatmaps. this offers some great 3d maps of select ski resorts across the world. Been using it to look over lines i have skied at Alta/snowbird this winter - you can tap on the marked trail on the map and it will give you the max gradient , distance , grooming status and all kinds of other info. You can also check out details on the verticle and length of your favorite lift - Take Wildcat at Alta:: verticle is listed at 1224 feet , the chair travels 3988 feet and has a capacity of 2 people ( for now at least)
there are other cool options like a fly by view of runs . still learning all the options myself. allows you to record your day as well.
just wanted to put the word out there that this is a very cool app for skiers, not affiliated with it or anything crazy like that .
i tried trace snow early in the season , but that doesn't compare
worth checking out
