I hiked to St. Mary's Glacier with a couple of friends. It is a short fifteen or twenty minute hike from the parking lot. It started off slow but eventually we found what was working. The previous time I there, I caught some very nice Tiger Trout. This time I had the camera and only got this one tiny Tiger, but a Tiger none the less. Brookies were also taking my FBBH Pheasant tails and midge emergers. Scuds in olive were working as well. If you like the Dry Dropper method than I would tie on an Adams in size 22 to 24. It is a fun and productive lake but the fish aren't real huge. A 3 weight was my choice of rod. A 9 foot Elkhorn made here in Colorado. Good Luck and tight lines!!
