thank you max and marty-- NY's North River (north of NYC it is commonly known as the Hudson River)--has a Palisades-- Steep high cliffs, they are so named be they in effect became a effective barrier-- the shores of the river north of what is midtown, about 42nd street-- on the NJ side of the river are high -- several hundred feet, sheer cliffs of cystaline granite. (Very similar to the "devil's steps stones" in North Ireland.) It is a ancient volcanic layer, that has be twisted and turn 90 degrees. A similar structure exist in northern Manhattan-- but not till 168th St--
the George Washington bridge-- (180th street) has almost no "Up Ramp" on either side of the river-- there is slight grade-- but not the steep grade common to suspension bridges-- the bridge is almost level the ground--until the ground suddenly drops away in a sheer cliff.
Very unlike the ANZAC, for example-- which was shown as one of the challanges in the Olympic Marathon race.
