 The name "mountain beaver" is a misnomer. They are not beavers but a type
 of borrowing rodent (Aplodontia rufa). They don't necessarily live near
 water, nor do they build anything from logs like true beavers. They look
 sort of like gophers but apparently have their own taxonomic line. See:

 And, from the above site:

 "Mountain beavers are not very social animals. Rarely do they go farther
 than a few meters from their burrows. Their home ranges overlap and each
 beaver defends its nest site. The sight and the hearing of the mountain
 beaver are very poor but their senses of smell and touch are well
 developed. Mountain beavers vocalize in the form of whistles and booming
 sounds. They also squeal while fighting and make a grinding noise with
 their teeth (Carraway, 1993)."

 So, "mountain boomer" might be a reasonable characterization of them, but
 I have never heard them called anything but mountain beavers.

 FWIW, they used to be considered a pest in Oregon when I was a kid because
 they would eat young plant shoots including fruit trees. As I recall there
 was a bounty of 25 cents for every carcass you hauled into Oregon City.
 I personally have never heard one make any noise at all, they're mostly
 nocturnal and are not commonly seen.
 I suspect that most everyone who has walked around the woods in the
 Pacific Northwest has stepped into a fair number of mountain beaver holes.
