Mercator inflates area by sec²(latitude): nothing on the equator, about double at 45°, and more than triple past 55°.
Because Wrangell–St. Elias National Park sits up at 61°N, the map is anything but honest here — it blows the park up to about 4.3× its true area, roughly 334% more than it really covers. That inflation is the whole reason it can look a giant beside Bhutan, which lies far closer to the equator and is drawn much nearer its real size. Drag it back toward the equator and the bloat drains away.
