Unfortunately these are mystery photos, with not a clue as to who or where. Well, there is a clue as to where - they are on a mountain and you can see the valley below.    They are all of a group of girls and young women, and their headgear tells us it was during the 1920s.  Maybe it is a Scout troop or a hiking club.  At any rate, the photos show us what girls were really wearing on rambles through the woods.  Note that at least one girl is wearing a skirt.
