Gary has been clever enough to eliminate our best guesses so far!
How about Hamal? 20 degress up, almost West, a good cross with Polaris. With GHA of 212 deg 24.9 min, it fits in his 17' to 26' window. Using a 208 reduction, one gets a Z of 75 deg. Since you're in North Lat, and the star is west, Zn=360-Z or 285 deg. Oops, forgot to bring down the 2 in the subtraction, used 85 by mistake. So, (without much checking!) I make them 21 miles further West than they thought. Probably not a big deal this far away. Anything else on the chart make this seem possible?
