||Old Faithful Museum, Upper Geyser Basin. (Set
speedometer at 0.0) The trip logged below is from Old Faithful Museum
and Ranger Station to West Thumb Junction on Yellowstone Lake, thence to
Lake Junction and on to Fishing Bridge Museum.
|Take road to the right for the housekeeping cabins, general store,
campground. This is the utility area for the Upper Geyser Basin.|
|Haynes Picture Shop on the right||0.15|
Ranger residence and entrance to Old Faithful Lodge on the left.
||Continuing straight ahead, we cross the Firehole River on bridge. From
here on for a number of miles we climb toward the Continental
|Kepler Cascade on the right||1.4|
These are cascades on the Firehole River
formed by water flowing over the harder rocks of a rhyolite lava
Road to Lone Star Geyser on right. The distance to Lone Star Geyser
from this point is 2.4 miles. The road is good but narrow.|
Lone Star Geyser has an interval of approximately three hours, although
it has been known to play after an interval of only twenty minutes.
Continuing on the road to West Thumb we find
rhyolite exposures to the left of the road. The
colors here are no doubt due to the action of hot
water and gases upon the old lava flows.
|3.2||Lodgepole forest to either side of the road.
|3.4||Three glacial lakes may be
noted here, two on the left of the road and one on the right.
glacial till on either side of the road.
|5.3||Glacial lake sediments on
either side of the road.
|5.5||Again we pass through rhyolite, the fine-grained
equivalent of granite. In Yellowstone Park rhyolite forms most of the
bedrock throughout the central part of the area.
|Norris Pass on the right, named by Colonel
P. W. Norris, the second superintendent of
Yellowstone National Park.|
|6.0||Going through Craig Pass. Named for
Ida M. Craig, the first white woman to go this way.
||Bridge crossing Isa Lake. Continental Divide,
Elevation 8,260. Lake drains from west end to
Atlantic Ocean, from east end to the Pacific
||The black sand found here on either side of the road is disintegrated
rhyolite and perlite, overlying rhyolite which has been acted upon by
Lake sediments and stratified sands on the left.
During the last Ice Age glaciers dammed up the valleys in this area to
such an extent that several high level lakes actually spread over the
|Shoshone Point. At this place we obtain a view of
Shoshone Lake and the Grand Teton Mountains. Shoshone Lake is about
three miles distant, whereas the Grand Teton mountains are about fifty
miles away. They form the central attraction of the Grand Teton National
Park. The Shoshone Lake drains to the Lewis and Snake Rivers and thence
to the Pacific Ocean.|
|Glacial Lake Beds on the right. The tremendous amount
of stratified sands in this area seems to indicate that a high level
lake existed here during glacial times and no doubt was a part of old
Shoshone Lake at a time when this body of water was greatly expanded due
to the melting of glacial ice.|
Again we have stratified and unstratified glacial drift on the left.
||Disintegrated perlite and rhyolite, the black sand at this place on
either side of the road, is the result of disintegration of former lava
||Continental Divide, Elevation 8,522 feet.
||Glacial drift on either side of the road.
||Directly ahead is Flat Mountain, which is on the south shore of Yellowstone Lake.
||Glacial drift on either side of the road.
A view of Yellowstone Lake and beyond it the Absaroka
Range. Yellowstone Lake has a shore line of approximately 100 miles and
an area of about 139 square miles. Its elevation is about 7,731 feet
above sea level. From this point we view only the western extension of
the lake known as West Thumb Bay.
Duck Lake on the left.
West Thumb Junction. The South Entrance is 23 miles
to the right, and Lake Junction is 20.4 miles to the left. Haynes
Picture Shop, campground, cabins, cafeteria and a general store are
located at this place. The ranger station is located about 100 yards to
the south of the Junction.
The Thumb Paint Pots, numerous hot springs, and
beautifully colored hot pools and several geysers may be seen in this
area between the Junction and the Lake shore. It is a weird and
fascinating area. Some places there is danger of breaking through the
crust, therefore it is advisable to follow the walks. There is good
fishing in West Thumb Bay.
||From West Thumb Junction we proceed to the left to Lake Junction and the
Fishing Bridge. (Set speedometer at 0.0)
|Occasional Geyser is just to the right of the road.|
|Deposits from the hot springs and geysers (geyserite) are found along
the road, particularly to the right.|
Here we have hot springs and colored pools on the left.
|There are also hot springs beneath the surface of the Lake on the
West Thumb Bay of Yellowstone Lake on the right.
From here to 3.0 along the left of the road may be seen decomposed
|The little island on the right is known as Carrington Island, and was
named for a zoologist who accompanied the Hayden Expedition in
|A good view of the Absaroka Mountain Range on the right.|
Old Lake deposits on the left.
||Here we cross Arnica Creek. This creek is named after the yellow flower
known as arnica.
|On the right is a natural wave-built bar used for a time as a wagon
||Pumice Point on the right.
|A good view of the Red Mountains across the Lake to
the south. Flat Mountain is the one toward the east and may be easily
recognized. The next one to the right of it in the distance is Mount
Hancock. The next to the right of that, and the commanding peak, is
known as Mount Sheridan.|
||On either side of the road one may see a mixed forest of fir, spruce and
lodgepole. Can you distinguish between them?
||Dot Island on the right.||10.7|
Glacial drift in cut bank on the left.
|The large island to the right and in the distance is Frank Island.|
|Here the long island to the right is Stevenson Island.|
|We are now going around the edge of Bridge Bay.|
To the left is the road to the Natural Bridge, which is approximately
two miles away.
Bridge Bay campground on the left.
One of the old Lake terraces may be seen on the left. This was formed
when the Lake was approximately 60 feet higher than it is at
|Boat house for U. S. Bureau of Fisheries on the right.|
Fish Hatchery on the left. You may park and see some typical trout and
observe how they are propagated.
|Parking area to the right. These boat docks are for official use by the
U. S. Bureau of Fisheries and the National Park Service.|
|At this point boats may be obtained for fishing or for trips out on the
