Fawn Lake and Blacktail Ponds present a somewhat different story. Both
are home to larger than average brook trout, and both are not good
places to take kids or beginning anglers, since each presents a fairly
serious danger. The former is a hike of 5 strenuous miles into the
Gallatin Mountains, an area literally infested with grizzly bears. The
last time I went to the lake my partner and I saw three grizzlies (and
several wolves, elk, and bison), for example, the last of which rose out
of the sage no more than 50 yards away. This is not a hike that should
be attempted alone or without bear spray. Blacktail Ponds --really one
pond with two pools connected by narrow point-- has slightly smaller
fish, averaging 12 inches, but they sit right below the northern leg of
the Parks Grand Loop Road. On the other hand, the pond is bordered by a
peat swamp, into which its possible to fall up to ones crotch and get
stuck without a buddy to pull one out. For this reason, its best to fish
this pond from a belly boat. Also note that its often closed due to
nesting rare birds, a closure not announced in the Parks regulations
booklet. Inquire locally to learn if this closure is in effect when you
visit.

You didn't get the memo.

Fawn Lake has been a weed-choked mud hole since the days of Jim Bridger.
In fact, some say that Fawn Lake was just one of Jim's famous tall tales.
