The original image was taken a little closer to the river bank, but the erosion of the river bank and the swift river current made this repeat photograph a little tricky. I decided against wading too far into the river to locate the original camera station. Original photograph used courtesy of the Grand Canyon National Park Museum.

My first trip across the Black Bridge (a.k.a. Kaibab Bridge) allowed me time to relax and reflect on the next phase of my repeat photography project -- Phantom Ranch. I stood their wondering how many tourists had made the passage through this tunnel and bridge previously. Original photograph used courtesy of the Grand Canyon National Park Museum.

The final descent: the Kaibab Bridge and the Colorado River. The shadow of the bridge appears roughly in the same position in this pairing, indicating that they were taken during the same time of day.

The original photograph taken after Tipoff on the South Kaibab Trail was captured a little further southeast (i.e. further back up the trail) than this repeat attempt. Attempting to do repeat photography with miles and miles of vast open spaces proved more challenging than performing the same process within the human-built environment.

Due to the distinctiveness of the switchbacks on the Kaibab Trail, the original camera station was much easier to find than most of the pairings taken on this excursion into the Canyon. A mule train packing out garbage, from Phantom Ranch, crossed my path about 10 minutes after taking the repeat image.

Based on the shadows visible on O’Neill Butte, the original photograph was taken during the early morning and probably during the summer months. The repeat was taken at 10:30am in March. The presence of snow and cloud coverage also diminishes the exactitude of the attempt. Original photograph used courtesy of the Grand Canyon National Park Museum.

The juniper bark roof has been replaced with composite roofing, and the vegetation has changed with the passage of time, but the day hiker can still visit this popular exhibit at Cedar Ridge. Original photograph used courtesy of the Grand Canyon National Park Museum.

This image from Ooh-Aah point greets hikers near the top of the Kaibab Trail. The repeat image should be retaken during the afternoon.

The "Chimney" is a series of steep switchbacks at the beginning of the trail guides hikers down the canyon. Since the Kaibab Trail lacks much sun exposure, it proved extremely icy during the early spring. I decided to return to the same location in May for a second attempt. The vegetation obscures much of the trail in this repeat image.
