Once you're set up with good optics, there's a certain method to finding good rams. Dall sheep will usually be up and feeding in the morning, early afternoon and evening, and those are the best times to spot them. Often, after not seeing anything for most of the day, the mountains will be full of sheep late in the evening. It doesn't seem like white sheep would be very hard to spot, but a lot of times they will bed down out of sight. Our basic method is to glass hard with binos, especially when they are active. In the area we hunt, most of the rams will be in grassy areas and draws near rocky crags and good escape terrain, whereas ewes and lambs will often be found at much lower elevation. The best glassing is usually from a high vantage, as a lot of the country is hidden from view when glassing from the river bottoms. But to conserve energy, I only climb if I need to.
