Collecting Cambrian Trilobites in the Spence Shale
This was my first trip of the year
into the material that has made us "famous". The Spence
Shale. Long hikes and hot days keep most people away from these sites,
but there are a few that venture up here. I didn't take any pictures
of the stuff we found, because it was one of those, not so productive
days, but the scenery was nice. I think the temperature was in the
upper 90's. A real scorcher when it is about a 2 hour hike. According
to some encyclopedias this mountain range, the Wellsville Mountains,
is the steepest in the world, based on a width to height ratio. |

A view from the bottom. The Spence Shale
is above the brown cliffs just right of center.
|
 |
| View from the middle
of the canyon looking up at the cliff forming Brigham Quartzite. The
Spence is mostly covered in the canyon. If you look you can see one
of our quarries just below the gray cliffs on the left side of the
photo. It looks like a small brown spot. |
 |
| A view from across
the canyon at the old Antimony Mine. It was active during both World
Wars. |
 |
| A view from near
the top looking down Antimony Canyon at the "road". |
 |
This little knob has what we call the Ogygopsis
Zone on it. It is the lowermost section of the Spence Shale that
we collect.
|
 |
|
View from the Spence Shale
at the "saddle". Since the Spence is softer than the rocks
just older and younger than it it has weathered faster. Once again
you can see the cliffs of the Brigham Quartzite, now below us, and
Brigham City, (hometown) in the background.

 |
|
And again.
|
 |
|
And again. The valley floor
is at about 4400 ft. we are at about 6400 ft. Over 2000 ft up. Thats
a long hike. The Wellsville Mountains are the steepest mountain
range in the world. They are tall, but narrow.
|
 |
| And again. |
 |
| One of the spots
that we quarried. |
 |
| Jake (right) and
Nick (below) Skabelund actually invited me to go with them on this
trip. This is the kind of place that requires a lot of hard work.
These guys are a couple of the few that venture up here. |
 |
|
 |
| On the way back
home. Jake in the foreground is carrying a Stromatolite from the Ute
Formation just above the Spence Shale, see below. Behind him is an
old mining "hotel". |
