Mussel Rock also know as the Dumps is an unrated site about 15 minutes southwest of San Francisco. Although this site is unrated in should be considered an advanced flying site and not flown by beginning pilots without the supervision of an experienced mentor or instructor.
Mussel Rock presents a number of unique dangers that need to be avoided. First there is the danger of being blown back into power lines which line the top of the cliffs or into houses. To avoid this happening always remember to be constantly alert to changes in wind speed while flying, also as you climb higher in moderate to strong wind always fly further away from the cliffs. Remember “Up and Out”.
Another danger is the ocean and more specifically the surf which you should do absolutely everything in your power to avoid landing in. Landing in the surf is often fatal. Always be conscious of how high the tide is. If you chose to fly during high tide be absolutely sure of your ability not to sink out on the beach if the wind is on the lighter side. If you do land in the surf your number one priority is to get out of your harness and away from your glider without getting tangled in the lines. Only after you are completely free of your glider should you even consider trying to retrieve your equipment from the surf.
