We live within a few blocks of the cache site, and have been wanting to hide a cache in this spot for several months. A few mutual hours opened up in our schedule last week after Jonster's school let out for the summer.
Depending on satellite conditions, you may find GPSR reception to be a bit spotty from time to time. We grabbed our coordinates on a good satellite day, and they should be fairly decent.
Bring your binoculars, camera and a picnic basket. Find the cache, eat some tasty things and enjoy one of Seattle's many fine views.
When searching for this cache, please remember that you are in an geologically unstable area -- you should not have to leave the path to reach this cache. Magnolia Bluff is basically a pile of sand on a sloping mound of clay left over after the Vashon glacier receded from the Puget Sound area at the end of the most recent Ice Age. This pile of sand continues to work rather hard to tumble down on Perkins Lane below, and then rejoin the sea. Please don't help this erosion in action by scrambling around or digging away from the path.
If you have the time, take a 1/2 mile stroll down to the southwest terminus of Perkins Lane, where there are still several sobering reminders of what a little sudden and catastrophic erosion can do to streets and houses, courtesy of the Great Storm of December 1996.
