Beach Walk and Super Moon

Last night I went on a beach walk with friends, Lois and Jamey.  It was an absolute gorgeous evening -- and there were no bugs!

A few feet more of sand is evident on my favorite beach, located east of Grand Marais.  Once we went down the bluff, we still have to walk east since there is no beach to the west.


Once we walked a quarter mile east, there was even some rock.


Enough rock, that Lois found a nice shadow agate.

 

Believe it or not, the fall colors are already starting -- probably due to the drought.


Jamey up on the bluff being Jamey....



At the bottom of the bluff notice the sedimentary layers that have bands of black sand.



The photos below could be macro shots of sandstone cliffs from out west.

 
 

White pine tree...


Driftwood sculpture...


Looking west toward town....


This mother killdeer bird was trying to keep us away from here nest.


 Heading back....



The sunset, still setting into the fog that is still out over the lake.








Sunday night entertained us with a supermoon. A supermoon is the coincidence of a full moon or a new moon with the closest approach the Moon makes to the Earth on its elliptical orbit, resulting in the largest apparent size of the lunar disk as seen from Earth. The technical name is the perigee-syzygy of the Earth-Moon-Sun system. The term "supermoon" is not astronomical, but originated in modern astrology. The association of the Moon with both oceanic and crustal tides has led to claims that the supermoon phenomenon may be associated with increased risk of events such as earthquakes and volcanic eruptions, but the evidence of such a link is widely held to be unconvincing. 


A supermoon is shown in the above photo in the right image, to show that it is larger than the normal moon's diameter.  The Moon's distance varies each month between approximately 357,000 kilometers (222,000 mi) and 406,000 km (252,000 mi) due to its elliptical orbit around the Earth (distances given are center-to-center).According to NASA, a full moon at perigee is up to 14% larger and 30% brighter than one at its farthest point, or apogee.

I took the pictures below from the sand dunes over Sable Lake.
