Indeed hunting from the "rock" is legal. I was in the same situation a few years ago, ie I observed a hunter on the rock with gun in hand near sundown. I visited the Shelburne police to inquire about the legality of this activity. They in turn contacted the VT F&W Dept, who responded that it was legal to hunt from the rock as long as the hunters do not point their guns toward the parking lot.

Subject: [VTBIRD] Hunter question
At the Shelburne Bay fishing access today at 3:00pm 2 hunters got out of
their separate trucks , each with a rifle and walked to the big rock at the
end of the parking lot and then walked out of sight down toward the water.
Is this an area that is open to hunting ?? Nancy Goodrich, Shelburne
