George Crowl, a former Explorer and Explorer Advisor from the "good old days of Scouting (back in the 50s and early 60s) had quite a few corrections and updates to the old pages on the various Exploring "square knot insignia." So, while I was editing the existing pages, I decided -- "let's give Exploring it's rightful due" and I built these pages around what he and another Exploring/Venturing historian Mike Brown (as well as my own personal bit of Exploring "history" and research) provided. He correctly wrote:

Your USSSP page has some incompleteness and inconsistencies. I refer you to Michael Brown’s excellent web site of Senior Scouting history . I personally am a Silver Award Explorer, Type 1, from 1953, so I lived the entire program from 1950 to 1958, was an Air Explorer, and was an Explorer Advisor from 1980-97, so have experience with the later program as well, helping two young women earn the Explorer Achievement Award.

I made corrections to the GOLD paragraph. I corrected the Ace paragraph, and replaced the private issue knot with a scan of a real Ace knot, but have had trouble getting rid of the private issue knot. I added a Ranger paragraph and knot. I corrected terminology throughout. I modified the Silver Award paragraph to reflect what actually happened. I added some information on the Explorer Achievement Award.

Second version of Exploring Silver Award, also used for several
other Exploring awards over the years -- and is currently being shared with the
Young American Awards.

I’m honored to give my thanks in acknowledging George Crowl’s contributions toward making this as accurate a review as possible!

Thank you so much for the additional information and the scans!.
