Beautiful marina here! Actually, this Boulder Marina and campground is one of several on the lake.
You can see how big this lake is--55,000 acres. I will come here again for a cheap and very clean and pleasant place to stay.
I left here and headed about 60 miles to the Cahokia mound site. Cahokia once had 20,000 people living in this huge city. There is an excellent museum here built and managed by the State of Illinois. It is a first-rate facility and well worth spending a couple of hours here. I am surprised that a state facility can be so well done!
OK, I admit to chickening out of climbing the big mound. I had a long drive to make and it was hot and muggy, so maybe another day.
Here is a very small sampling of some of the excellent exhibits inside the museum:
I liked this last exhibit showing how they excavated the mounds.
