I guess you must have driving well passed the simple ford on Old Balt.Rd. The boulders at the crossing I thought had been there for years. I seem to remember them being there a long time (I crossed that spot often on my way to either White's Ferry ro up Rt. 28.
traveling westbound the land to the left of the road (south side) is part of the Black Hills Park. To the right is private property. Because this stream feeds into the larger lake and there is a lot of ecological restoration and studying going on there, I would not be surprised if they saw something (extra silt or something) and closed it. Or someone got stuck, had to get fished out, someone got word and closed it due to liability. I certainly wish there was more options too, however...aside from just the pure joy, if you find yourself with a Jeep and little to no use worthy of retaining it. I know that kinda comes off sarcastic, but I don't mean it to be. Just means it might be time to evaluate things.
