Nature Now Radio Interview: Port Townsend Geology on KPTZ 91.9 FM





I recently had the opportunity to spend an afternoon at the KPTZ 91.9 FM studios in Port Townsend with Mary Robson, one of the Nature Now radio program hosts, to discuss Port Townsend's geology. There was so much to talk about - there were 2 radio segments that came out of it.

You can listen to the two Nature Now segments about Port Townsend's local geology as archived podcasts, the links are provided below. Thanks again to KPTZ.org and Nature Now for having me on their show!

Below is a photo from the studio, that's Mary Robson on the right.

Girls Scouts Rock Out at Fort Worden

I had a chance to lead 12 enthusiastic local Girl Scouts on a guided tour of the beach geology from North Beach to Fort Worden on the morning of Saturday September 24. Those girls were amazing at identifying rocks and their questions about the visible landslides were excellent. I hope they keep their zest for rocks and geology - there's a need for more geoscientists in the future.

And I really appreciate the thank you cards I received :) !

You found a cool rock or fossil - can you keep it?

You just found an amazing rock or fossil and want to keep it. But can you? The answer in Washington State is...it depends who owns the land.

Below is some information about Washington State rock hounding, mineral and fossil collecting on 1) federal, 2) state and 3) private lands taken from the agency websites. Click on the links for more details.

If rules don't allow you to take your treasure home, you can still take a photo to remind you of your great find. By respecting the rules and leaving the rock, gem or fossil behind, someone else will be able to share the same excitement when they find it.

1. FEDERAL LANDS

Are you on Federal Land that is a Park, Monument, Refuge or Tribal Land?
Below is a list of Federal public lands managed by the Federal Government that do not allow rock hounding or fossil-hunting. If you find something here, you need to leave it.
National Parks
National Monuments
National Wildlife Refuges
National Scenic Areas
Tribal Lands

Are you on Federal Land managed by the Bureau of Land Management?
You can collect up to 250 pounds of rocks, gems and specimens for personal, non-commercial use from BLM land annually without a permit. You can use hand tools such as shovels and picks, but no power equipment for excavation. (Commercial uses of rocks and specimens include selling, trading or bartering them.)

Are you on Federal Land managed by the US Forest Service?
You can collect a reasonable amount of rocks and minerals for personal or hobby use from most National Forest Service lands without a permit.  The reasonable amount is defined as 10 pounds. You can collect samples from the surface only - no digging, even with hand tools - when on Forest Service land. You can collect common minerals, as well conduct recreational gold panning and collect gold and other naturally occurring metals.

You can collect fossils of plants, clams and insects (non-vertebrate only) from Forest Service land. You will need to get a free-use permit if you want to collected petrified wood (wood that has been fossilized by silica) for personal use.

You cannot collect fossil fish bones, shark teeth or other vertebrate bones from US Forest Service land, and you cannot collect Archeological artifacts such as remains of prehistoric or historic human life or activities (anything older than 50 years). Arrowheads cannot be collected, they are also considered human-modified stone.


2. STATE LANDS

Are you on Washington Department of Natural Resources State Lands?
State lands managed by the Washington Department of Natural Resources (WA DNR) are host to amazing agates, amethysts, garnets, jaspers, opals, and even gold nuggets. Washington State also has an array of fossils including crinoids, clams, trilobites, snails, corals, and at least one dinosaur.

The following specimens cannot be collected from DNR land without a permit due to their rarity: meteorites, vertebrate fossils, or any archeological or historic artifacts.

If you want to collect for hobby purposes from DNR land, check out DNR's online rockhounding and fossil map. Permits are issued by region, and Port Townsend is in the Olympic Region.

Are you in a State Park?
You must have a permit from the State Parks to collect any minerals or fossils.

Why? Any finds on State Lands are considered public property. In 2015, a therapod dinosaur fossil was found in Sucia Island Marine State Park in the San Juan Islands by Burke Museum staff. The therapod family of dinosaurs includes the carnivorous velociraptor. Cool! This dinosaur find will remain in the collection of the public Washington State Parks collection for all residents of Washington to enjoy in the future. The dinosaur femur is on display now at the Burke Museum in Seattle.

Are you on County or City land?
Then you need to check with the folks at the local city or county permitting office. Local rules vary.


3. PRIVATE LAND
Before entering private land, you must ask the landowner for permission. Private land owners include farmers, forestry companies and residents. No trespassing!

It is illegal to remove cultural artifacts from public land or from private land you do not own. Take a picture, get the GPS coordinates, or draw a map and notify the public or private landowner. Contact the Burke Museum to help you find the correct public landowner, or to help you identify an artifact or fossil.

If you own property and mineral rights, then you have the right to collect on your property or to give permission to others to do so. If you are not sure if you own the mineral rights to your property, check the property deed, or contact your County Assessor’s office.

Mining claims (both patented and unpatented) are considered private lands, and you must obtain the owner's or claim holder's permissions before proceeding.

If you want more information on how to obtain a commercial collecting permit, check mineral rights for your land, or file a mining claim or mineral lease on public land click here.


Obey the collecting rules, the fines are steep!

Free Guided Geology Beach Walk at Fort Worden State Park - Sunday June 12 at 2 pm


All ages are welcome!

I will be leading a free guided geology walk of the lower beach at Fort Worden State Park Sunday June 12 at 2 pm in Port Townsend. We will look at the glacial clay and peat layers exposed by a landslide just north of the beach campground area.

The guided geology walking tour will be about 1/2 mile total distance and last about 30 minutes. Stay after to beach comb and identify rocks from the Field Guide to Port Townsend Rocks and Geology. Low tide is at 4:13 PM on June 12.



Click here for the full-size Fort Worden Trail Map.

The guided geology walk will start from the paved parking area about 200 feet east of the beach campground loop. This is a rain or shine event - so bring your raincoat just in case.

In 2010, I taught a "Geology of Port Townsend" Course through Peninsula College. The Fort Worden beach landslide deposits (called "Qls" on geology maps) was one of our class field stops. Below is a slide that gives some background information on what we will be looking at June 12.

You will need a Discover Pass to park your vehicle in the lower beach area. You can purchase a pass the same day of your visit from the Friends of Fort Worden Gift Shop located inside the park. Gift Shop address: Fort Worden State Park, 200 Battery Way, Port Townsend, WA 98368.

Upcoming minus tides are good for beach hikes


Photo: View facing east towards Fort Worden State Park on a stormy day in March 2016. At right, layers of peat within the Whidbey Formation are exposed.





The best time for beach hiking is during low tide. And the best of the best low tides are called "minus tides." The next predicted minus low tide in May 2016 for Point Hudson in Port Townsend is Friday May 20 at 9:58 AM at -0.1 foot. As spring turns into summer, the low tides will get even lower. The lower the tide, the more area of beach is exposed and better access around points and headlands.

All tidetables are "predictions" - this is because local storms, high winds and barometric pressure affect the actual tide level on any given day.

Use the link below to look up predicted tides - or you can pick up a paper copy of a local tidetable in a marina or hardware store once you arrive at your destination.

After you click on the link, scroll down to the section called "Admiralty Inlet" (because that's where Port Townsend is). Then click the town or area closest to where you will be walking.

There are two low tides and two high tides in every lunar day (24 hours 50 minutes). There are many, many days over the next few months with minus tides -- but the list below gives you the "lowest of the low" minus tides in the near future.
