Hammonasset (Captions Transcript) Intro Ralph: Here we are at the Meig’s Point area of Hammonasset State Park. What we have here is a long pile of boulders along the shore, which extends offshore towards Faulkner’s island in the background. Many of these boulders are quite different from each other, and they form a huge pile. What do you think happened in the past to cause what we see here now? Hammonasset: Rocks: Bedrock Ralph: Here we are in front of the bedrock just north of the boulder field at Hammonasset. You’ll see that it’s a salt and pepper black and white color because it’s predominated by quartz and mica. It’s also lightly banded or foliated. Check out the zoom tool and the rock chart to see if you can ID this bedrock. Bedrock Acid Test Ralph: Okay, let’s do the acid test on this bedrock outcrop. Well, it didn’t fizz, so it can’t be marble or limestone. Hammonasset: Rocks: Boulder Field Ralph: Here we are in the middle of the boulder field. It’s a long narrow band that extends along the shore, and it even can be seen out off shore as those boulders sticking out behind me. From this vantage point the boulders all look fairly similar, but as we take a close look you’ll see there are some very striking differences in them. Hammonasset: Rocks: Boulder 1 Ralph: This is one of the largest boulders here. As you can see, it’s rounded, it’s about four meters in diameter, and these color bands are derived from the minerals that make them up. We have pink feldspar, some mica, and some quartz. Check out the zoom tool and rock chart to identify this rock. 1 Boulder 1 Acid Test Ralph: Let’s do the acid test. Well, it didn’t fizz, so it can’t be limestone or marble. Hammonasset: Rocks: Boulder 2 Ralph: Here’s a medium sized boulder. It’s rounded, about a meter in diameter, and it has sort of a black and white salt and pepper look because of the minerals that make it up, predominately quartz and mica. Check out the zoom tool and rock chart to identify this rock. Boulder 2 Acid Test Ralph: Let’s do the acid test on this medium boulder. Well, it didn’t fizz, so it can’t be marble or limestone. Hammonasset: Rocks: Boulder 3 Ralph: Here’s a medium sized boulder. It’s rounded, about one meter in diameter, and it has this rusty brown color because it has high iron content, so it’s stained. Check out the zoom tool and rock chart to identify this rock. Boulder 3 Acid Test Ralph: Let’s do the acid test on this stained boulder. Well, it didn’t fizz, so it can’t be marble or limestone. Hammonasset: Rocks: Boulder 4 Ralph: This small boulder is a little bit different. It’s very round, as you can see, and it’s quite smooth. The small crystals that make it up give it a very uniform gray color. There’s no banding or foliation. So check out the zoom tool and rock chart to see if you can identify this rock. 2
