No, these are not cicada-related wounds. Instead, they appear to be human-caused, though by what means we're not sure. If damage this deep encircles enough of the tree's trunk (called "girdling") at some point in the future, it will kill the tree.

In areas with high human visitation (like along trails, pathways, parks, etc.), tree scarring from vandalism (initials carving being the most common form this takes) is common. The injuries we see in the images are not insect or bird damage or a result of infection, though it's possible infection or decay-causing organisms can find an easy entry point at such wounds. Bears would be the only animal causing scratch-like gashes of this magnitude in bark of older trees, and this does not resemble black bear damage. (Plus, while they can pass through many counties in the state as they wander and find territories, it's unlikely such repeated damage was done without anyone having spotted the animal. There are both fresh and old marks on these trunks.)

Some land managers employing certified pesticide applicators can try to control invasive weed-tree species via a "hack and squirt" herbicide method, where wounds from axes or similar tools are made and a dose of herbicide administered to the wound. This not only facilitates chemical uptake with no risk to surrounding plants, but also reduces the amount of herbicide needed. If this were the case here, however, signage may have been posted cautioning passers-by if the application were recent enough. (The hazard window would likely have only been hours long.) Some herbicides also include a dye so the applicator can keep track of exactly where applications were made. However, since the public setting of this site makes such treatment unlikely (as the park staff would then have to have the dead tree removed so it's not a fall hazard), it's more probable that if trees were designated for removal that they would have been cut down outright. Similarly, since some of these scars are many months or years old and on multiple trees, it's unlikely such hack-and-squirt efforts would have been that ineffective while still being attempted again and again.
