OK, you have just made me Google "How fast can a moose swim?" Never thoughtWhat I've been too lazy to do so far is to transfer this motion to a map and figure out the speeds involved. I don't believe a swimming moose would be fast enough.
https://www.tetonscience.org/can-moose-really-dive/We also know moose are incredible swimmers, at least as hoofed animals go. They are capable of hitting speeds of at least six miles per hour. That sounds like no more than a jogging speed for humans, but most humans can only swim two miles per hour. High School swimmers hit three to four miles per hour. Olympic swimmers win medals above five miles per hour. So moose are pretty fast swimmers.
Elsewhere in the article it confirms that moose can dive, though they have to work at submerging due to various moose-boyancy factors that might derail the thread into duscussions of moose density, so I will omit them.
