This image shows the beautiful valleys and peaks in this desert like foothills terrain.What it also shows unfortunately is the amount of infestation the Pine Beetle has made especially in this region.
Excerpt from a B.C. gov't. report:
Spread of the Infestation

The most recent surveys show about 9.2 million hectares of B.C. forests – an area nearly three times the size of Vancouver Island – in a stage of red-attack (meaning the trees are dead and the beetle has moved on). This is up from 8.7 million hectares in 2005. The epidemic has killed an estimated 582 million cubic meters of merchantable timber, equivalent to 15 years of normal harvest for the Province’s central and southern Interior. The outbreak continues to kill mature pine trees in the central Interior and is well established in the Thompson-Okanagan and Kootenay regions.The epidemic will only be over once it has infested most of the mature pine in B.C. Ministry of Forests and Range analysis shows that, at the current rate of spread, 80 per cent of the merchantable timber in B.C.’s central and southern Interior will be dead by 2013. In a large portion of the epidemic area, pine makes up over 50 per cent of the harvestable timber.
