The 1869 Labatt map and the 1871 Birdseye View of Galveston place the GH&H depot between 33rd and 35th streets at Market St. These Galveston maps can be found online at the Perry-Castaneda map collection of the U of Texas Library. It appears that Ave A or Water st, where the later depot was located, was still in the bay in 1869-1871.
