The rangers are talking about leaving it there to decompose. Fortunately LaSalle turned out to be right. By press time almost all of the carcass had decomposed and washed away. As for the driftwood, it's still there this year. If you drop by, see if you can find the hammer and nail sculpture reported on the beach in April.
Rangers patrol the area on foot and horseback.
Park in the dirt parking lot just up the road. Take the trail at the far end of the lot. You can stop at a bench along the way to see a nice view of the Marin Headlands. After another 100 yards, past the trash cans, the path narrows and bends, passing a clump of fennel, then rises and falls, eventually becoming the width of a road. Don't take the road on the right, which leads to a golf course.
