Ohio Petrified Wood Part 2 - Psaronius

Back in the early 1980s, I went on several collecting trips to the Barnesville, Ohio area to hunt for petrified wood but never found any.  Last year (2018) , I finally acquired several pieces of 'Barnesville' petrified wood which is a fossil fern trunk and root clusters of Psaronius.  The wood is typically very dark brown to black with clear to white patches of quartz.

I bought the first two pieces from eBay, abit pricey but I've seen so little of it for sale over the years.
Afterwards, I bought three much larger pieces from the Stark County Mineral show (April 2018) in the silent auction.  My final piece which is the largest, my wife found at the Hartville Flea Market in June 2018 for a bargain price of $20.00.

If you find yourself in northeast Ohio in late March April, I recommend the Stark County Mineral show.

Scot's Bay Nova Scotia - Bay of Fundy Area

Travelling for work gave my wife and I a chance to visit area of the world I have always wanted to visit, Bay of Fundy...

In my research, I found what looked like an idea spot, Scot's Bay.  It is on a piece of land that juts out into the Bay of Fundy on the north western coastline of Nova Scotia.

Rob's Rock shop - Collecting Locations along Bay of Fundy

My wife and I flew from Cleveland via Toronto to Moncton, New Brunswick.  New Brunswick and Nova Scotia part of the Atlantic provinces in Canada with very scenic landscape even along the main highways.  Flying time from CLE to Moncton was ~3.5 hrs.   Travel time from Moncton to Scot's Bay was ~3.5 hrs.

The beach area is large more than a mile across and is covered in nothing but gravel and cobbles.  Even though is was still cold ~55'F in the 3rd week of June, it was still very enjoyable to comb the beach seeing the great varieties of rock types reflecting the local geology as well as the rocks brought in by the powerful tides in the bay. Below, is a geological map of Nova Scotia list gold deposits.  Bay of Fundy coastline along western Nova Scotia is composed of Triassic-Jurassic age basaltic rocks. The basaltic rocks are the local source for amethyst, agate ans zeolites that can be found along the beach.

On the tides in the Bay of Fundy, the area experiences the highest tide differential on earth.  Tides top out at 50 feet above low tide twice a day!.  This is the result of moon's actions on the earth's oceans as well as the funnel shape geometry of the bay.

When we first arrived at the beach, it was about 1 after high tide, so the water did appear to be receding.  We collected for about 1.5 hr before stopping for dinner.  After dinner, we drove out to the trail head to Cape Split (which was unfortunately a 4-5 hr round trip) but as we parked, we saw something amazing.  The water had retreated nearly 25 feet vertically and exposed an amazing basaltic landscape that spends most of the day underwater.  We spent until sunset wandering over the basalt outcrops!  As a geologist, truly one of the more unusual spots I have visited.

We did find a piece of the elusive Bay of Fundy amethyst more agate but definitely purple in color.
Also found a nice large piece of banded agate similar looks to Brazilian agate I've seen.

We could only take a few pounds of the best material we collected since we were travelling by air but the link below is a rock photo collection from Scot's bay.

I would recommend this location to anyone who enjoys rock and mineral collecting or just beach combing in general.  I would love to visit this area again.

DRC 3.0 Update - Build 3.19 is Available

 I just released the latest update to Digital Rockhound's Companion Version 3.19

   -  DRC installer no longer requires a DVD
   -  Changed Updater to automatically download to DRC folder again.
 The Full installer and Updater has several improvements
  - No DVD required.
  - Street level GIS files have been removed.  There files were first added back in 1997 when DRC was an MS Access app.  Some might remember this version.  It had its merits, plus reporting was easy with MS Access reports.  I still miss that feature(sigh...) The streets GIS files were rendered moot a decade ago by Google Maps.
 - DRC Updater.exe is smaller.  Finally solved a 'free' hosting solution for files.  Its amazing in 20+ years of the Internet, it has become increasing difficult to host a file over 200MB. Every one wants to extract a fee for hosting.  Since DRC is a barely for profit operation, I choose not to spend any profits on site fees.

I'm not going to post a link for DRC installer or DRC Updater.  If someone cannot download DRC updater please email me at Please include DRC in the message status/header.
