s in the older literature. This is due to their location at the exit of some of the glens or directly opposite them. The relationship between the Glenblocker forts and the Gask Ridge has in the past been seen to represent a staged withdrawal. More recent research suggests that the three elements are actually part of the same frontier system, stretching roughly from Loch Lomond to Montrose. The Glenblocker forts in this scenario control access to major valleys in the frontier area, which actually loop back into the frontier area, rather than link to the Iron Age settlement concentration further north). Their role as an effective block to invasion is doubtful, as their situation would have allowed supervision, but their manpower is not strong enough to deter anything but small scale cattle raids.
