The Miles brothers based their business out of Earl's home, and shot more film of post-earthquake scenes; some of this footage, including that of a second trip down a now devastated Market Street, reemerged in 2016.

Film historian David Kiehn noticed that there were puddles of water seen in the street, and after he examined contemporary newspapers and weather reports, he realized that the early estimates were wrong: no rain had fallen in those months.

[9] In 2009, Kiehn suggested that A Trip Down Market Street was filmed in late March or early April 1906, a period with many rainy days reported.

Kiehn also found a San Francisco newspaper article published on March 29, 1906, describing the Miles Brothers' intent to film aboard a cable car.

[12] In 2011, Richard Greene, an engineer with Bio-Rad Laboratories, published research dating the film to March 24–30, 1906, based on the sun throwing well-defined shadows on the Ferry Building.
