With stopovers at Huntington and Ebensburg, where they stayed several days waiting for Bodmer and Saynisch to catch up with them, Maximilian and Dreidoppel reached Pittsburgh around midnight on September 26. Securing accommodations at the Exchange Hotel, they were soon joined there by Bodmer and Saynisch.

On the afternoon of August 2 71 Maximilian and Bodmer explored the banks of Tobyhanna Creek, and Bodmer made a sketch of the bridge crossing it. Maximilian commented in his journal that Bodmer waded several times across the stream until he found "a favorable spot for the view. The rest of us were looking for birds and plants." Another view of this bridge was reproduced as Vignette IV in the atlas of plates that accompanied the publication of Maximilian's journal nearly ten years later.

Moncasa Creek, a tributary of the Lehigh River, separated Lehigh and Northampton counties and divided the town of Bethlehem itself. Bodmer's pencil sketch of the bridge over the Moncasa at Bethlehem was made on or before July 28.
