Donna, although they abut one another (separated by US Hwy 2), the Bob is quite different from GNP. They are about the same size, but where GNP has stunning peaks, valleys, and lakes, the Bob is mainly just a huge and wild forested place with few people. True, there are plenty of decent mountains, but few that compare to the grandeur of Glacier. But wild it is. I don't know how much of it burned this summer, but I think the Gates Park area got hit pretty bad.
And don't forget about Yellowstone. It's a different type of ecosystem than Glacier, but so very wild in its own right. Critters of all shapes and sizes, forests (some burned and recovering, some virgin old growth), a few good mountains, vast meadows, lakes, great rivers, and waterfalls. And on top of all that, it sits on a huge active volcanic formation, with incredible geysers and fumeroles to entertain you in the backcountry.
