What water feature was there before the lakes were formed?

b. they tried to evict the squatters from the area.

so sorry if wrong

the national congress's powers over the states were specific and definite: it had the sole power to negotiate treaties, declare war, and make peace. all powers not granted to congress were reserved for state governments. congress had no power to levy taxes, for example.

how is this a question? but yes, they were. if i recall correctly, it was very handy for native americans to use buffalo skin.
