I was looking at the satellite views of Bath tub/Barth hot springs last night.
It appeared the map had it located where you describe, around the bend on the left.
I remember climbing up a short creek bed to the tub with the drain plug.
Have fun on your MF trip. Hopefully I'll get a chance to meet up with you when we take out on the 2nd.
