[edit] Description

These three rock outcroppings are the last in the chain that make up the Thousand Islands. Enter the water here by boat and then just drift with the current. The depth starts at 50' and gradually drops to 90' with the current taking you mainly on a compass bearing of 60.

[edit] Access

This is a boat dive, with charters available from Saint Lawrence Park.

[edit] Hazards

Drifting in the current will usually work, but use a compass to make sure you don't (a) entering american waters (south) or (b) drift into the shipping channel (north).
