¿Types Of Puzzles? - 7. You're A Puzzle Master!! Mystery Cache

Welcome to Stanaback Park. This cache was hidden in conjunction with GC8HKCQ, ?Puzzled? - A Community Celebration Event. This is the bonus cache for finding all 6 caches in the series.
 

This puzzle is a "bonus cache" type. A bonus cache is a special type of mystery that requires you to complete a series of caches that typically culminate with a final find. In most cases, each cache along the way will give you some sort of information that you will have to accumulate together and earn or solve the final bonus coordinates. In this case, each of the preceeding 6 caches contain a letter and a number on the first page of the logbook. Assemble them as follows to find the bonus cache!
