Photograph of children on the shore of Lake Huron in Ontario, Canada in July of 1929. The bedrock shale has been eroded and is now exposed in the foreground. Large concretions sit on the beach and in the shallow water near the shoreline in the background and trees cover the landscape behind the rocky shoreline. Jefferson would often use the same negative to create a lantern slide as well as a mounted stereographic card. When possible we have indicated if it is a repeat image, however this is not always the case. As such, there may be a corresponding digitized glass lantern slide, and a mounted stereographic card associated with this stereographic negative within the Mark Jefferson Collection.
