What astronomical holiday isn’t better if rounded out with a little poetry? Admire the massive forces at the edge of our daily living, and recite some beautiful poems into the crisp, shadowed air. As Mabel Loomis Todd, friend of Emily Dickinson, said, “I doubt if the effect of witnessing a total eclipse ever quite passes away… A startling nearness to the gigantic forces of nature and their inconceivable operation seems to have been established.”

A Solar Eclipse, by Ella Wheeler Wilcox

In that great journey of the stars through space
     About the mighty, all-directing Sun,
     The pallid, faithful Moon, has been the one
Companion of the Earth. Her tender face,
Pale with the swift, keen purpose of that race,
     Which at Time’s natal hour was first begun,
     Shines ever on her lover as they run
And lights his orbit with her silvery smile.

Sometimes such passionate love doth in her rise,
     Down from her beaten path she softly slips,
And with her mantle veils the Sun’s bold eyes,
     Then in the gloaming finds her lover’s lips.
While far and near the men our world call wise
     See only that the Sun is in eclipse.

The cache is not located at the posted coordinates - Mars has nothing to do with this eclipse event!  You will need to bring a pen to sign the log though.  You need to figure out the final location using the following string of text:
