Commemorates Captain Patrick Logan an explorer in Southern Queensland.
In July 1830 Logan led an expedition to the headwaters of the Richmond River and on his return, since the regiment was due for transfer to India, he attempted to chart the windings of the upper Brisbane River. He never succeeded for, he was killed by Aboriginals on 17 October in the region of Mount Beppo.
Captain Patrick Logan. This plaque was erected in remembrance of Captain Logan, an enthusiastic and energetic explorer of Southern Queensland. Captain Logan made two expeditions up the Brisbane and Stanley Rivers, and visited the group of hills located to the east of this plaque naming them "Irwin`s Range". This range includes the high rocky outcrop of `Glen Rock` located north-east from Glen Rock. It is said that Captain Logan may have climbed Glen Rock the afternoon before he was attacked and murdered by Aborigines whilst camped at Logan Creek on 18 October 1830. The erection of this cairn and plaque was proposed and funded by Mr Douglas Jolly, a person keenly interested in the history of Queensland and a member of the Royal Historical Society of Queensland. He unveiled this plaque on 28 October 1984.
