avoid the "Telfer's Rock" on the left at Blossom Bar.

I thought Telfer Rock was the left-side obstacle at the 2nd S-turn
of Mule Creek Canyon. Easy to miss, but potentially lethal to swimmers
without PFD. Save your wrists for Coffeepot, where speed helps.

You are right Bill. Telfer's is in the last of the S-Turns in Mule
Creek Canyon - Above Coffee Pot. I think being too far left or
hitting it sideways would mean a sure swin in an OC.
