In this part the question in discussion, is there any indication the Bigfoot might also build some kind of underground lairs with many different hidden entrances to avoid detection? The answer is, since I have not witnessed this nor found a lair, I can only answer as to what I have observed.
The Arizona Bigfoot does seem to dig, but they do not dig like rabbits with front and back entrances. When they do dig, it is usually to create a hunting blind, a shelter, or a trap. I have located two types of hunting blinds one of which involves digging a hole, and the other requires a tree to be pushed over across a ravine which has a game trail running through it. The hunting blind may be at the base of a fallen tree where the root ball and start of a hole is available. They burrow under the root ball and create a hole big enough to lay or crouch without being seen. They enhance the hiding place with broken pine brow branches stacked up against the root ball to create an entrance which is usually topped off with a trap door to hide them until they are ready to spring out.
To make the blind more effective, they will spend days and months slowly building a barrier to funnel the animals past the hunting blind. These barriers will be constructed out of trees and limbs over time to allow the resident animals to get use to the barriers being there and not arouse any suspicion of the intended prey. It is also interesting to note the dirt from the hole will be removed and scattered over the forest floor to hide the evidence of the hole.
The second hunting blind is just a tree pushed over a ravine with certain key branches removed to allow the Bigfoot to lay on the log and remain hidden at night. The animals are either driven by other Sasquatch under the log where the Bigfoot lying in wait simply drops down onto the back of the animal. Imagine an eight hundred pound Bigfoot landing on the back of a deer or elk. No most of the kills I have located have broken front legs or a broken back.
As for the shelters, they usually minimize the digging efforts by finding a log or tree fall in which they burrow under and create a comfortable den. Many times they will cover it with pine brows and fill it with fresh soft leaves to lay on.
The traps usually are a hole dug in the dirt approximately three feet in diameter, and two to three feet deep. These traps are used to break the legs of any fleeing animal the Bigfoot chases through the area. They are basically “fall” traps, or “break leg” traps.
The digging implements are usually their hands, but there has been many broken sticks found near the holes. It appears they start out with a long stick and use a chopping/stabbing action to soften the dirt to where they can remove the dirt with their hands. Therefore, their digging abilities are limited and probably do not permit the digging of elaborate tunnels.
