In "Race at Morning" Hog Bayou camp is where another group of "five or six" hunters are camped during the hunting season (301). It is "eight miles below" the narrator's camp (300). Ordinarily each group would stay away from the other groups stands and guns, but the buck the narrator and Mister Ernest are chasing leads them right through this party.
In "Race at Morning" this is the "ridge" that "runs due south" down which the buck runs after getting past "Uncle Ike's standers" (300). It is "clear of vines and bushes," which allows Mister Ernest's horse to "go fast" (300).
The hunt in "Race at Morning" can be said to begin when the narrator and Mister Ernest reach the woods on the far side of the bayou and turn back into these woods toward the place where they know the buck is sleeping.
A deer-hunting 'stand' can be a structure, a platform attached to a tree that allows the hunter to wait a dozen or so feet above the ground for his prey to walk past - or the term 'stand' can simply mean a specific place on the ground, usually against a tree, where the hunter waits. In the Yoknapatawpha fictions it usually is the second kind of 'stand' that is meant. In either case, it's a safety precaution: when a group is hunting together, as is also the usual case in Faulkner's fictions, by staying at their 'stands' the hunters know where the other hunters are.
A "fire road" in the woods is meant to provide access to equipment in case of a forest fire (298), and can be little more than a widened path. The one in "Race at Morning" seems to run parallel to the river.
A "bayou" is a swamp-like body of water, sluggish or stagnant, usually adjacent to a river (298). In other fictions Faulkner usually uses the term 'slough' for this natural feature. It can be shallow enough to wade or, like this bayou in "Race at Morning," deep enough to swim a horse, and it can be big enough to contain, as this one does, "a little canebrake island" in its middle where a deer can make its bed (299).
In "Race at Morning" the hunter's two horses are tied up or hobbled in a "feed lot" across the river from their camp (307), to be ready for each day's hunting in the "big woods" (309). The narrator feeds them corn that is brought into the woods before the last day's hunt begins. The "landing" for the boat that carries the hunters back and forth across the river (307) is "down the bank" from this lot (296).
Although "the river" in "Race at Morning" is never named (297), there is a good chance that it is the Sunflower River, which flows through Mississippi about 150 miles southwest of Oxford/Jefferson and into the Yazoo River about twenty miles east of the Mississippi. Faulkner himself hunted along the Sunflower in the mid-20th century.
"Race at Morning" takes place long after the hunting camp that Major de Spain built on the site of Sutpen's fishing camp has disappeared, and far enough away from "Yoknapatawpha" to suggest that it's in the Delta region of Mississippi, perhaps on the Sunflower River (where Faulkner himself hunted in the mid-20th century). Unlike "Delta Autumn," where the hunters set up tents on their arrival for the annual hunt, the "camp" in this story seems to be a permanent and fairly big set of structures.
