No sooner had I promoted your Sunday Puzzler as a fun learning tool to my high school age daughter, when, for the second week in a row, she questioned “Isn’t Crater Lake (Ore.) the deepest lake in the lower 48?” (not Tahoe, Feb. 1) and “Doesn’t three trimesters fall short of a year by three months?” (Feb. 8).
