Then let me give you an example or two.
Early explorers to the south shore of Lake Erie noted the presence of bison in that area. While apparently no one recorded it, it’s fairly certain that the Buffalo River and its tributary Buffalo Creek got their names from those animals. Later on, a town was founded along Buffalo Creek and took its name from that stream. Hence, Buffalo NY.
This pattern of naming land forms after animals found in that area was repeated over and over again across the country. It wasn’t always just a prevalence of the animal, sometimes there was an unusual encounter between an explorer and a specific animal. Either way, we have a plethora of rivers, creeks, lakes, hills, mountains, ridges, bluffs, cliffs, falls, etc. named after wolves, elk, beaver, otter, deer, moose, cougar, etc. And sometimes towns take their name from those features, as in the case of Buffalo.
Similarly with plants. There are numerous land forms named for those, especially trees, but also flowers, bushes, etc. But also just a grove of some kind of tree where a town was founded gives the town its name. Hence various tree names like cedar, oak, maple attached to Grove as town names. Or even without the “Grove”; Catalpa MO and Catalpa NE were named that way, for example.
While these kinds of names are very common, they aren’t the only descriptive names out there. Anchorage AK was a good place to anchor ships, for example. There are others, as the submissions to this thread illustrate. But as I said earlier, among town names, descriptive names are second most common only to places named after people.
