Jeff Batten (Juan de Fuca) Memorial Thread

Over the years I have sent 10 reports to the NPS detailing the severe
risk of the Lost Arrow Spire.

I have included the simulations that prove that the tensile strength of
the granite on the NE flank is approaching the failure value of granite.

I have pleaded they install a GPS receiver to monitor the tilt.

My current calculations prove that any earthquake within a 60 km radius
with a magnitude of greater than 6.5 will cause the spire to fail.

With many active faults in the mammoth area I grow very concerned.

The computer simulations assuming an isotropic granite place an upper
limit on the failure. We all know granite contains many cracks.

Assuming a failure drop to the south west, my fortran computer
simulations predict that the talus cone created will cover most of the
Yosemite Village. Deagans appears to be ground zero. Over a billion tons
of granite will fall. The acoustic wave alone will be recorded by
senstive seismographs 1000 km away. The seismic signal will probally be
recorded on the east coast of the united states. El Cap meadow will have
50 cm of granite dust deposited alone.

With proper funding the spire can be stabilized. We envision large
dampers that will absorb any seismic energy. Two can be placed in the
notch. The entire structure needs to be wraped in iron mesh.

Please write the NPS, and demand that they act before its to late.

As for climbers, if you have to do the spire, do not rig a tyro.
The torque will be more than enough to cause failure.

"All the world's a stage,
And all the men and women merely players;
They have their exits and their entrances;
And one man in his time plays many parts,
His acts being seven ages. At first the infant,
Mewling and puking in the nurse's arms;
And then the whining school-boy, with his satchel
And shining morning face, creeping like snail
Unwillingly to school. And then the lover,
Sighing like furnace, with a woeful ballad
Made to his mistress' eyebrow. Then a soldier,
Full of strange oaths, and bearded like the pard,
Jealous in honour, sudden and quick in quarrel,
Seeking the bubble reputation
Even in the cannon's mouth. And then the justice,
In fair round belly with good capon lin'd,
With eyes severe and beard of formal cut,
Full of wise saws and modern instances;
And so he plays his part. The sixth age shifts
Into the lean and slipper'd pantaloon,
With spectacles on nose and pouch on side;
His youthful hose, well sav'd, a world too wide
For his shrunk shank; and his big manly voice,
Turning again toward childish treble, pipes
And whistles in his sound. Last scene of all,
That ends this strange eventful history,
Is second childishness and mere oblivion;
Sans teeth, sans eyes, sans taste, sans everything."

— Jaques (Act II, Scene VII, lines 139-166)
