At Spanish Banks, one has a safe spot to observe a full tidal cycle and its effect on sedimentary bedforms. Repeated visits are required to observe the evolution of the beach sand. Experiments either involve manipulation of the surface to see the tides' effects on the manipulation, or a mere observational experiment to make measures of sand formations caused by tides.
In these mountain catchments there are opportunities to observe stream activity and slope failures. Some hiking skill might be helpful, as the site is at about 600m above sea level.
Pictures are on their way!
