Well there ya' go, a well, Duh, moment. In Feb. if there is any snow, even the small chunks would sit in little snow melt craters, and the U of I at IA City is maybe only an hour from there by horse and carriage, And IA hasn't changed much from the ol' days, still one boooring SOB in the Winter, it was probably big doings to go find pieces when there weren't much else to do. Others may know better, but methinks the IA River runs through bluffs around those parts and maybe the base of blffs might have somethin left. Would need some research on immediate weather and snow cover, old news to estimate the percentage of recovery. You sure have been a help in this, Thanks, nimby
