to Day 7 Photo Overview
Photo
1: At the pullout just before the Park entrance, between mileposts
89 and 90 you can see possible Saurapod tracks (a trample bed) on the north
side of the Fremont River (across the river from the road). The trample
bed is located in floodplain deposits just below the resistant sandstone
at the top of the photo. Both the floodplain and the sandstone are part
of the Salt Wash Member of the Morrison Formation.
Photo
2: Navajo Sandstone makes up the Capitol Dome in Capitol Reef
National Park. Here it is as seen from the Hickman Bridge Trail.
Photo
3: Basalt boulders along Fremont terraces derived from the
Aquarius Plateau. These are Tertiary (?). They are remnants of the old
Fremont channel.
Photo
4: Navajo Sandstone with joints with Entrada Sandstone at the
top. The Navajo Sandstone here has its typical rounded appearance.
Photo
5: Hickman Bridge in Capitol Reef National Park. As viewed
from the west.
Photo
6: Hickman Bridge in Capitol Reef National Park.
Photo
7: Hickman Wash in Capitol Reef National Park.
Photo
8: Mud lenses and rip up clasts that are now weathered out
and outline cross bedding near Hickman Bridge parking lot. These features
are in the Jurassic Kayenta Formation.
Photo
9: Mud rip up clast in the Jurassic Kayenta Formation.
Photo
10: Petrified wood in the Triassic Chinle Formation.
Photo
11: Outcrop of the Chinle Formation along the north side of
the road in Capitol Reef National Park.
Photo
12: Tracks in the Triassic Moenkopi (Moody Canyon or Torrey
Member). This fallen slab is near the pullout on the south side of the
road just west of the Chimney Rock parking lot. Hike towards the south
to the wash and at the outcrop on the east side of the wash look at the
fallen slabs.
Photo
13: Plant fossils along the base of a bed in a fallen block
at the same site as described in previous caption.
Photo
14: Fossil in block near cabin at Visitor's center.
Photo
15: Grand Wash from pullout to the hiking trail on the east
side of the road. In the photo the Triassic Moenkopi is at approximately
road level, it is overlain by the Shinarump Conglomerate, the rest of the
Triassic Chinle Formation, and the Jurassic Wingate Formation (the cliff
former at the top of the photo).
Photo
16: View from Goosenecks Point. The Permian White Rim Sandstone
is exposed at the base of the cliff and it is overlain by the Permian Kaibab
Limestone. The Kaibab is unconformably overlain by the Black Dragon (lower),
Sinbad (gold color), and Torrey Members of the Triassic Moenkopi Formation.
Photo
17: Looking east from Sunset Point. Stratigraphy as described
in the above caption. This site is located just west of the Waterpocket
fold that marks the western boundary between the desert and the high plateaus
of the Colorado Plateau physiographic provinc e. This is a good area to
use the surrounding geomorphic features to interpret the time of uplift
of the Colorado Plateau and incision of the streams that cut through it.

18: A slightly zoomed-in version of the photo described above.
Photo
19: Permian Kaibab Limestone in Suphur Creek Canyon.
Photo
20: Permian Kaibab Limstone in Sulphur Creek Canyon from Sulphur
Creek. Note the bent strands of grass that provide evidence of flash floods.
Photo
21: Evidence of flash floods along Sulphur Creek.

22: Coyote footprint along Sulphur Creek floodplain.
