Were you logged in to a geocaching.com account when you looked at the map? If you weren't, that could be the reason why you're not able to see the geocaching info.
Here's another link you could try: http://www.geocaching.com/seek/nearest.aspx?lat=48.356567&lng=-123.726783
. It shows the geocaches near the spit as a list, and not on a map.
