I'm looking at making a 2-3 day trip to the wind river range in late August. Since I'm not familiar with the region and my guide book hasn't arrived yet, what should I be expecting to be in for?

Are the mosquitoes still bad in late August?

What are the temps that I should be prepared for? (I assume being ready to be comfy at 20* for sustained time will be enough, or is that over/underkill)?

What about rain, just the afternoon shower, or will I have a decent chance at seeing the flood gates open up?

Whats the bear situation like (pesky bears, or just stealth it and most likely won't have problems)?

How's the water situation?

Will I still have to deal with some snow, or should it be gone for the most part by then?

Any special gear (other than good camera) that I should bring?
