I was reminded of the Olive Matuka the other day. This was a very popular streamer pattern back "in the day"?
On a trip into the West Yellowstone area, I stopped in all the fly shops in town. Not a single Matuka pattern.

I spoke with Aaron at Arricks fly shop. He said that some year he intends to use all the old patterns as he is sure they will still work well.......yet, he doesn't carry them.

I would post a picture of one the way I tie it, but haven't had time to tie any lately.

This used to be a very good producer for me on the Western waters.
