bend or extreme of Lake Michigan". When Congress passed the Enabling Act of 1802, which authorized Ohio to begin the process of becoming a U.S. state, the language defining Ohio's northern boundary elaborated on that, but was fundamentally the same: "an east and west line drawn through the southerly extreme of Lake Michigan, running east ... until it shall intersect Lake Erie or the territorial line [with British North America, now Canada], and thence with the same through Lake Erie to the Pennsylvania line aforesaid". The most highly regarded map of the time, the "Mitchell Map", showed the southerly extreme of Lake Michigan at a latitude north of the mouth of the Detroit River, suggesting that an east–west line would not intersect with Lake Erie at all, until well across the international border. The framers of the 1802 Ohio Constitution therefore believed it was the intent of Congress that Ohio's northern boundary should certainly be north of the mouth of the Maumee River, and possibly even of the Detroit River. Ohio would thus be granted access to most or all of the Lake Erie shoreline west of Pennsylvania, and any other new states carved out of the Northwest Territory would have access to only Lakes Michigan, Huron, or Superior. However, the delegates allegedly received reports from a fur trapper that Lake Michigan extended significantly farther south than had previously been believed (or mapped). Thus, it was possible that an east–west line extending east from Lake Michigan's southern tip might intersect Lake Erie somewhere southeast of Maumee Bay, or worse, might not intersect the lake at all; the farther south that Lake Michigan actually extended, the more land Ohio would lose, conceivably even the entire Lake Erie shoreline west of Pennsylvania. Addressing this contingency, the Ohio delegates included a provision in the draft Ohio constitution that if this report about Lake Michigan's position was correct, the state boundary line would be angled slightly northeast so as to intersect Lake Erie at the "most northerly cape of the Miami [Maumee] Bay". This provision would guarantee that most of the Maumee River watershed and the southern shore of Lake Erie west of Pennsylvania would fall in Ohio. The draft constitution with this proviso was accepted by the United States Congress, but before Ohio's admission to the Union in February 1803, the proposed constitution was referred to a Congressional committee. The committee's report stated
