Photograph of a large boulders taken in Colorado. The rocks are light in color and show signs of weathering and erosion. Sparse vegetation can be seen in the midground. Large mountains rise in the background. 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.

Rocky landscape in Wu-tai-shan of the Shan-si province in China. It is noted that the lands at the base of the deforested mountains are buried in waste. Large boulders and rocks cover the barren landscape, and several buildings and stepped agricultural fields can be seen at the base of the mountains. There is no vegetation.

Photograph of a canyon taken in Colorado. There are large boulders and vegetation on near the camera. Large canyon formations stand to the left and right of the camera. 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.

Photograph of a river taken in Colorado. The river rushes over boulders and rocks. A large glacial deposit can be seen in the background. 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.

Photograph of a mountain landscape taken in Colorado. Large boulders made of Gneiss, Schist and other metamorphic rock stand in the foreground. Large mountains rise in the background. 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.
