Charbonneau Park was built by US Army Corps of Engineers on the Snake River. More precisely, next to Lake Sacajawea, which was formed behind the Ice Harbor Lock and Dam. It is not very close, but not very far either – we drove just a little bit more than 30 minutes right after I woke up from my nap. We got into the lake, then we spent the rest of the day playing with sand: I helped daddy build the biggest sand castle that Lake Sacajawea has ever seen. We got home pretty late and I went to bed more than one hour later than usual.
