Photograph of a cacti bush taken in Colorado. The cacti grows behind a wire fence. A stand of trees can be seen in the midground. 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.

Photograph of a desert landscape in the mountains. Cacti and scrub bushes cover the landscape around the cacti. The hills and mountains in the background are also covered with cacti. Power Lines can be seen next to the roadway in the foreground.

A close-up image of a cactus in the Badlands of North Dakota. It is noted that the picture was taken in July of 1924.

The cactus is in bloom and is surrounded by other low-growing vegetation.
