[QUOTE="BrentM, post: 1802191, member: 61747"] It may seem like that is the case but it rarely is. I am in Idaho shoot mountain terrain as well so I am well aware of your issues. To complicate it I hunt all winter for wolves where it is a little harder to read wind. No vegetation, mirage is weird, etc. I always start with prevailing wind and then apply general rules such as: there is always a up or drown draft, there is always a back draft, there is always a velocity change on open slopes or fingers, there is always a wind hide, there is always wind. 1. Read wind speed at the shooter 2. Figure wind speed at mid point and bullet flight path 3. Read terrain changes and if possible vegetation....usually pine trees 3. Read mirage. Wind flows much like water and flows around and over terrain features. It usually travels up/down draws/valleys, up/down the sides of ridges/fingers, usually back drafts on the back side of terrain features opposite of prevailing wind direction, and wind in the first of the flight path is more important than the second half but needs to be accounted for. For example if you need 2 moa in the first half L to R and 2 moa in the 2nd half R to L, you will still need to dial left about 1. Often people will cancel wind and send it, and be wrong. [/QUOTE]
