Brian Hausback's 1987 Fieldtrip Guide Here
We will camp on Friday and Saturday at
one of the campgrounds on the north side of Medicine Lake (the Hemlock
Campground or the A.H. Hogue Campground). Some of us will arrive early
to reserve enough sites for everyone. As you enter the area, look for
information posted on the main bulletin boards.
Some of us will head up towards the area on Friday
morning, stopping at Lassen National Park. Brian Hausback will lead us
to Bumpass Hell Hot Springs or to the top of Lassen Peak. We plan spend
Saturday at Medicine Lake, exploring sites throughout the volcano
(Glass Mountain, etc.). Finally, we will head the Fleener Chimneys at
Lava Beds National Park to explore caves before driving home.
There are several possible activities in the area,
including (but not limited to) canoeing on the lake, hiking, biking,
4wd touring, or lounging around camp.
Directions
To get to
Medicine Lake from Sacramento, drive north on I5 and then head east on
Highway 89 for about 26 miles to the town of Bartle. Turn left (north)
on Harris Springs Road, and after about 4.5 miles turn left on Mayfield
Road. After about 3 miles, turn right on Medicine Lake Road. You will
then reach the lake after about 20 miles.
Fees
The Alumni will wave the
camping and Saturday night meal fees for all geology students joining
us this year. Brian Hausback is organizing transportation through the
Geology Department for student attendees.
For Alumni and Faculty, the
cost of the trip will be the same as for all previous years. Adults
will be $25, $10 for youths, and no charge for babies and toddlers.
Those modest fees will pay for camping and a great Saturday night
dinner. Please bring your check payable to the CSUS Geology Alumni
Association to the campsite.
Who's Going? We Need a
Head Count!!!
In order to reserve enough campsites and buy enough
food for everyone in the group, we need an accurate head count. Please
email
us or call Geoff at (805) 320-3973 if you plan to join us.
Medicine Lake Geology
(From: U. S. National
Park Service Website, Lava Beds National Monument, 2001.)
The
Medicine Lake shield volcano, a sleeping giant, is the largest volcano
in the Cascade Range. Filling up the entire southern skyline, it has
been erupting off and on for half a million years. The eruptions were
gentle rather than explosive like Mount St. Helens, coating the
volcano's sides with flow after flow of basaltic lava. This created a
shield-shaped mountain approximately 150 miles around the base and 7900
feet high. Medicine Lake is part of the old caldera, a bowl-shaped
depression in the mountain. It is believed that the Medicine Lake
volcano is unique, having many small magma chambers rather than one
large one.
