Noticeable yes, obvious no. I seriously doubt you’re going to notice century old wood chips and markings on trees. Similarly large branches would look like fallen trees in other forests. A given section may not have seen anyone in 30+ years, others would have more noticeable impact but you’d have trouble seeing the logging vs all the trees. There would be remnants of trails and even some fresh ones, but that doesn’t specifically imply logging.
