thanks everyone.
when i spotted him he ws laying down. i used a verbal cow moose call to get his attention,and then a few male grunts brought him closer.i used to hunt these eons ago,when i lived up there so know their habits very well.he still has the velvet on his antlers so the rut is not on yet,thus i was in no great danger. besides i was about 10 ft from the van. he came close enough for these pics.i,d say whitin 100 ft.i was using a 400 mm lens,and canon 7-d for these shots.
