He spent the winter in a tribal village in what is now eastern Iowa. The next spring he encountered James Tute and James Stanley Goddard, who had been sent to accompany Carver on his journey. They continued exploring and mapping up the Mississippi River through what is now Minnesota, and Wisconsin. They then headed for Grand Portage on Lake Superior, hoping that Rogers had sent supplies there for them. However, instead of supplies they found a letter from him chiding them for having spent as much money as they already had and warning them to be more thrifty in the future. Unable to proceed without the badly needed supplies, they headed back to Fort Michilimackinac, arriving there on August 29, 1767.
