Hi,

Can someone explain to me the markings on these LEH zone maps. This is an example from 3-32 goat LEH zone map

I'm not sure what the following mean:

1. numerous little purple dots/circles within the zone
2. blue slashes (as far as i understood the blue "X" meant it was a snow field or glacier?)
3. The numbers on the map like this "3" on the lake here



Thanks guys!
