Hikers, do you want to learn a bit of field geology and map reading skills while hiking, and sometimes camping in the western USA? Interested in participating in Geo-hikes and trips to scenic, and sometimes remote, locations? Want to learn about the fascinating history of the earth at these locations while on the move? If yes, then events hosted and led by the Geologic Maps Foundation might be of interest to you. Plus, the participants meet others with similar interests while getting great exercise. You do not have to be a geologist to attend but an eagerness to learn some basic geology and map reading skills are a must.

Professional geologists can share their knowledge and experiences (as co-leaders) with geology students and non-geologists while exercising and returning to, for many, why they got into geology in the first place.

Geology students (at any level) will gain field experience, an opportunity to interact and make contacts with professional geologists that could be helpful in the future, and with lots of outdoors exercise in interesting geologic settings.

There are a number of geo-hikes scheduled for the 2020-21 season and more will be added. "Spreading the word" about these events is most appreciated. Interaction of professional geologists and geology students with hikers, that are not geologists, informs the public about geology and its importance.

Geo-hikes has limited the size and frequency of its events due to concerns about the spread of COVID-19. Events are still happening but are following more restrictive guidelines that are posted with the event summary.

Most of the Geo-hikes events and courses are free while a few are fund-raisers and require a donation to cover expenses and operating costs for the longer trips. The Foundation is a tax-exempt nonprofit ,IRS 501 (3) (C), with a scientific educational and research focus. Donations are tax deductible and go towards the expenses of the event and the operating cost of the Foundation.

Geo-hikes also organize and lead customized geologic field trips for professional organizations and companies to various areas in the western US and Baja California. Trips are great educational and team building experiences. Please email us at: geologicmapsfoundation@gmail.com for more information about the customized trips.

Ventura hillside Geo-hike

Hillcrest Drive

Something new: a 4.5 miles hike to communication tower above Ventura, ~900 ft elevation gain, pace is about 2 MPH. Most of the route is along an old dirt road and the route traverses the south limb of the large Ventura anticline. There are great views from the top. This is limited to a small group so no guests. Dogs must be on a leash the entire hike.

COVID-19 SAFETY REQUIREMENTS ON THE HIKES (THIS IS IMPORTANT TO KEEP ALL OF US SAFE AND ALLOW GROUP HIKING AGAIN). SOCIAL DISTANCING REQUIRED (6 FT OF SEPARATION), DON'T BUNCH UP ON THE TRAIL, IF YOU ARE FEELING SICK STAY HOME!

Boney Range Outlook Hike

Hike is into the northwestern portion of the Boney Range where we reach a beautiful 360 degree viewpoint! If it is clear we'll get great views of the Conejo Valley and the northern Channel Islands. This hike does not reach the crest of the Boney Range but it is great workout and provides a close look at a relatively remote area that it is still close to urbanization. This hike is a moderately strenuous for an evening hike, 7-8 miles with an elevation gain of nearly 2,000 ft, and the pace will be about 2.0 MPH (expect to be on the trail for 3 hrs). Hike traverses the Conejo historic Danielson ranch area and we will be doing the standard route (that is no Fossil Trail), that is in-and-out along the same trail. Please pack a head lamp or flashlight, it will be dark on last part of hike.

Directions: Take Highway 101 to Thousand Oaks. Exit at Wendy Drive. Go south (towards the ocean) on Wendy all the way until it dead ends at the Santa Monica Mountains National Recreation Area. There is ample free parking on the dirt along Potrero road. There are no restrooms at the trailhead.

Essentials: This time of year you don't need much, but make sure you bring a comfortable amount of water(1-2 liters for most of my hikes). Dress yourself with So Cal hiking attire, and be willing to get a good workout!.

Chorro Grande trail to Pine Mtn Ridge and back.

Chorro Grande Trail

COVID-19 SAFETY REQUIREMENTS ON GEO-HIKES (THIS IS IMPORTANT TO KEEP ALL OF US SAFE AND ALLOW GROUP HIKING TO START UP AGAIN):
CAR POOLING NOT RECOMMENDED FOR NONFAMILY MEMBERS
LIMITED TO 10 (INCLUDING LEADER)
SOCIAL DISTANCING REQUIRED (6 FT OF SEPARATION)
DON'T BUNCH UP ON TRAIL
PLEASE DON'T SHAKE HANDS OR HUG
NO SHARING SNACKS.
NO SHARING DRINKS.

NO CELL COVERAGE AT THE TRAILHEAD

Let's hike the Chorro Grande trail to the Pine Mtn ridge line (5.5 miles on way, plus 3236 ft up) so 11 miles round trip. Pace will be moderate (2.5 mph), but this a fair amount of up so make sure you know your limitations. Weather forecast is for a mid-day high in 80s in Ojai so it should be in the 60s-70s for hike, but it could be windy. The trail is along the southern flank so its well exposed to the sun. There may be a few small snow patches at the top.

At the Pine Mountain Ridge crest are great panoramas of the local ranges. To north we peer into the Cuyama badlands, and to south possibly see the Pacific Ocean and northern Channel Islands. The Chorro Grande trail traverses the southwest flank of the Pine Mountain Ridge. Along the way we will cross the Pine Mountain thrust fault and some interesting Eocene and Oligocene marine formations with their layers dipping southward. Pine Mountain Ridge is large anticlinorium (an arched upward crustal-scale fold) created by movement on the underlying Pine Mountain thrust, and the Chorro Grande trail traverses the southwest limb of the fold.

NOTE: YOU NEED TO BE IN GOOD HIKING CONDITION FOR THIS ADVENTURE. THE PACE IS ABOUT[masked] MPH, IT'S UP MOST OF THE WAY, AND STEEP IN A FEW PLACES. THERE WILL BE NO SWEEP AND IF YOU CAN'T MAKE IT TO TOP OF THE RIDGE YOU WILL NEED TO RETURN TO THE CHORRO GRANDE TRAILHEAD VIA THE TRAIL WE WENT UP, SO PLEASE PAY ATTENTION TO YOUR SURROUNDINGS ON THE WAY UP.

Bring plenty of water, boots, snacks, and lunch. It should be sunny and possibly warm, so a hat and sunblock are recommended.

Please be prompt for meet-up point. We do not wait.

Telescope Peak, Death Valley

Wildrose Campground

THIS EVENT IS NOW FILLED AND CLOSED FOR RSVPS (9/2021).

PLEASE READ THE BELOW:

There's a wait list for this event and the most active members of Geo-hikes have priority plus the group size will be small. If you have never done a long hike with Geo-hikes then please provide a short description of your hiking abilities. Keep in mind this is not an easy hike and most of the trail is above 9,000 ft where many find long hikes difficult.

We'll hike to the top of Telescope Peak (11,049 ft) in the Death Valley National Park on Friday 10/1. It's a 14 mile roundtrip hike from Mahogany Flat with a net elevation gain of a tad over 3,000 ft (It's the same trail to the peak and the return to Mahogany Flat). Our meetup point is is Wildrose Campground at 5:00 PM on Thursday 9/30, we'll camp there Thursday and Friday nights. At Wildrose the campground sites cannot be reserved (first come gets the camp sites) and one of the reasons this event starts late Thursday afternoon (Wildrose does fill often on the weekends). On Friday morning we can the decide which vehicles to take to the Telescope Peak trailhead at Mahogany Flat (8133 ft), the upper portion of the road is rough and high clearance vehicles do best. On Saturday morning we will do some short hikes and a geologic field trip in Wildrose Canyon, then return home.

This is car camping and you will need to bring all your meals, and camping items. Potable water is available at the Wildrose Campground. There are fire rings at the campground so please bring firewood.

Weather for the hike should be in 70's and 80's and very sunny (there's little shade on the trail), so bring lots of sun protection and water. There is a slight chance that it could be in the low 90s midday, possibly very windy, or a thunderstorm (we'll not be taking any risks with that and will call the hike if there is a chance of a thunderstorm). Please check the weather right before trip: Google search, mahogany flat campground weather

WARNING: TELESCOPE PEAK, MAHOGANY FLATS, AND WILDROSE CANYON ARE IN A REMOTE PORTION OF THE DEATH VALLEY PARK (SOUTHERN PANAMINT RANGE). YOU'LL NEED TO LOOK AT A ROAD MAP IN SOME DETAIL BEFORE DRIVING OUT MAKE SURE YOUR VEHICLE AND ITS TIRES ARE IN GOOD SHAPE. TAKE PLENTY OF WATER IN YOUR CAR FOR THE DRIVE OUT. IF YOU WANT TO BE ON A PAVED ROAD ALL THE WAY TO WILDROSE CAMPGROUND THEN TAKE HWY 190 FROM HWY 395, JUNCTION IS JUST SOUTH OF OLANCHA. ON THE OTHER HAND IF YOU TAKE THE HIGHWAY 178 THROUGH TRONA YOU'LL BE ON A GRAVEL ROAD IN LOWER PORTION OF WILDROSE CANYON. KEEP IN MIND, THE SLOWER ONE DRIVES ON GRAVEL ROADS THE LONGER BETWEEN FLAT TIRES. BY THE WAY, CAN YOU FIX A FLAT? YOU'LL BE DRIVING THROUGH THE PANAMINT VALLEY AND OTHER DESERT VALLEYS THAT ARE STILL HOT THIS TIME OF YEAR (+100 F). THERE IS NO CELL COVERAGE IN WILDROSE CANYON AT THE TRAILHEAD, ON MUCH OF THE TRAIL, AT THE CAMPGROUNDS, OR IN MUCH OF THE VALLEYS. ON THE CREST OF PANAMINT RANGE I SOMETIMES GET CELL COVERAGE BUT ITS SPOTTY.

You are responsible for all your meals and getting to the meetup point-make sure you understand the route there and if you haven't been there before I advise against driving in the dark.

It's truly amazing the amount of cross county hiking in extremely rugged and complex terrain these geologists accomplished.

Please do not sign-on to this hike if you are not very serious about going, know that you won't be called for work or have the possibility of other last minute issues that prevent you from going (be fair to others that end up on the wait list).
