Join Les Tyrala, Professional Geologist on this Quincy Environmental Treasures Tour and explore an old quarry and other interesting rocks at the "Crusher" site.  View the stories these rocks can tell of ancient volcanoes, primitive marine life and glaciers! 
This site contains a small quarry that was operated by the Tide Water Broken Stone Company from 1905 to 1912, and produced crushed stone (aka, traprock) for road grading and aggregate for making concrete. We will see direct evidence of a rapidly changing geological setting in what is now referred to as the Boston Basin. Within this southerly part of the basin, we will look at ancient lava flows (extrusions) in contact with the approximately 400 million year old sedimentary rocks derived from low-energy muds and sands deposited in bays to high-energy cobbles and boulders deposited by rivers. Additionally, we will interpret how the last glacial age, receding from Massachusetts about 9,000 years ago, shaped the site by observing the local glacial features.

Preregistration is required for this program.  Limited to 15 attendees. This program has been extremely popular and there is always a waiting list.  In order to accommodate as many people as possible, the tour is repeated every couple of years.  Because there have been people in the past who have been registered and not shown up or called to cancel preventing others from attending, I have added the following requirements.

Registration requirements:

1. Send an email to sallyowe@hotmail.com providing the number of people who will attend and a phone number where I can reach you the day before the tour to confirm your attendance.

2.  Agree to email me as soon as possible if you, or any member of your group can not attend, so that someone else on the waiting list can come.  If you are canceling the day before the tour or the day of the tour, call or text 617-347-4641.

3. Participants who have taken the tour before are not eligible to take it again.

4. All participants must be 12 years or older and children must be accompanied by an adult.  Sturdy footwear and the ability to walk on rocky ground is required.

Sally Owen will send you an email with the meeting place if you have made it on to the tour.
