The small ledge ESE of E Goose Rock, and another just E of Saddle Island, at first glance appear to uncover at low tide (based upon their asterisks), whereas my paper chart indicates they still have 3 and 9 feet over them, respectively...

I'm not familiar with Garmin charts, and precisely what those crosses represent... My guess is that the ones surrounded by a circle of dots actually uncover, whereas the cross without the circle does not, although indicates a rock just below the surface at MLW... Pretty good depiction, actually, if I am interpreting than correctly...
