I know this is a place I've blogged about before. Living fairly near it, we tend to go in that direction from time to time...it's worth the drive. And, I always end up sketching the same scene...well, who wouldn't. From a distance the main Rock formation looks small(ish), but when people walk around and stop at the top, then you get to appreciate the scale of the place.
Again, of course, I have done a quick sketch....very painterly this time and not detailed
