Sorry, I don't know any of them.I grew up in my father's gold mines in Hope and out from Fairbanks.He was in Alaska from about 1920 to WWII and then went back as soon as he could afterwards and mined some more.The last mine before the war was at No Grub Creek & the Salcha River.He probably knew your father.
The boots most of the men wore in the second picture are called "Shoe pacs".They have rubber bottoms and leather tops that lace up.Usually they were worn with a couple of innersoles (felt or something)& one or two wool socks to keep the feet warm and dry--particularly in winter.
Dad did what is called "Placer Mining".By the way, those water cannons are called "Giants". Dad used three or four to wash dirt and rocks to and through the sluice boxes.He usually had 8 to 12 men working 2 shifts.
That is probably more than you wanted to know but it certainly brought back memories.The trees in the background in the second picture are typical of the Fairbanks area.(I went to high school there.)Thanks. Fay
