Amiel Weeks Whipple
Whipple’s name is frequently heard in discussions about the Southwest, especially in connection with the Joint Boundary Commission of 1848. He was reported to be at Cooke’s Spring on June 21, 1851, and at the Copper Mines, thereafter. He was a surveyor and led major surveying expeditions in this general timeframe. He departed the Copper Mines on August 27, leading the astronomical function of the party performing the survey of the Gila. He appears not to have done much natural history work other than cataloguing specific geographic locations.

Henry Cheever Pratt
Personal Narrative of Explorations and Incidents in Texas, New Mexico, California, Sonora, and Chihuahua. At page “x” (page 26 of the .pdf), Bartlett acknowledged the work of Pratt. (See below.) At the bottom of this page is one of Pratt’s paintings from this period, “View In The Canyon of the Coppermines, Santa Rita, New Mexico”.
John James Abert
At the time of the Survey, John James Abert was the head of the Corps of Topographical Engineers and was involved in many of the key decisions associated with the Survey because of that. The Abert’s Towhee was named for his son, James William Abert, who was not associated with the Survey. (See earlier entry on James William Abert).
Although Pratt was an artist, not a naturalist, his renderings are some of the best available from the Bartlett explorations. At least 30 of his illustrations are found in Bartlett’s
