This is basically two swaps combined into one: one around the YC resort which doesn't seem controversial, and the one in the Crazy Mountains. The YC is involved in the Crazies to help equalize the swap around their resort. The swap isn't giving the Yellowstone Club any lands in the Crazies. In fact, it is the opposite: the YC gave up a section of land with Smeller Lake on it, and are paying for a new trail. But their involvement tainted the whole exchange even if it added value.
A little more detail about the swap is here.

I haven't looked at it enough to comment in depth, but I did see they addressed the comments about wetlands, conservation easements, and water rights.
