hey, I think I know where 55 flag was. Got more info. Was the flag quite close to the creek? not really the bottom part of a reentrant, but more of a stony erosion ditch of sort? and was there some vegetation, maybe a downed tree log or something? I was upslope and could not see the creek, that was close. It seems that the flag was placed not at the center of circle, but 7 meters south of center of circle, where that bushy part / tree log / vegetation is . Does this jog your memory ?
