OAKLAND CEMETERY
EARTHCACHE REQUIREMENTS
Each cacher must send his/her own answers BEFORE logging a find. ... "Geocachers must complete the tasks before they log the EarthCache as found." (4.3. EarthCache logging tasks)
Enjoy the journey (learning adventure) as well as the destination (smiley earned). Remember to take only pictures and leave only footprints. To get credit for this Earthcache, complete the following tasks:
1. MESSAGE …. Look at all sides of the boulder. Describe all the types of weathering that is responsible for changing this rock.
2. MESSAGE …. Based on your observations, which type of weathering (mechanical/chemical/biological) is having the greatest impact. Explain.
LOG …. Post a picture of you or your signature item at the Memorial honoring American Veterans (waypoint). This picture is your log signature.
OPTIONAL - Please respect the time and effort involved in finding and creating this earthcache by adding A B C to your log.
A. Visit a memorial honoring our fallen heroes. Post a picture at the memorial. Label picture with name and location of memorial.
B. JOURNEY OF THE MIND ... Science explains what we observe. Relate (in your own words) something you found interesting in the reading. This adds to your learning adventure and your log.
C. JOURNEY OF THE HEART ... Art shares our personal experience of what we see. Share something special you found on site, and why it is special to you ... prose / story / poem / picture. This is a memorable addition to your log and will make other hearts smile.
Journeys of Heart and Mind ...

THANK YOU Cemetery Personnel for permission to share this learning adventure.
THANK YOU Jim for sharing information on this gravesite.
QUARTZITE CONGLOMERATE BOULDER
While walking the land collecting hickory nuts in the late 1800s, Crandall came across this huge boulder. He immediately puchased the entire surrounding plot and made the boulder into a natural columbarium (storage of cremated remains). This is the only above ground boulder in this cemetery, the largest one in the entire county.
WEATHERING
Weathering is the breaking down of rock into smaller fragments. All rock weathers over time. Grains of sediment fall out. Cracks develop on the surface and deep inside. Weathering causes rocks to fracture, buckle, and crumble into soil and sediment. There are two types of weathering - mechanical and chemical.
MECHANICAL WEATHERING
Mechanical weathering breaks apart rocks without changing their chemical composition. Each fragment and particle weathered away by a mechanical process retains the same characteristics as the original rock.
TEMPERATURE - Different minerals expand and contract at varying rates. Temperature changes occur in both day-night and seasonal cycles. Frost shattering or ice wedging is due to the expansion of ice.
WIND - The abrasive action of wind causes separation of rock particles from the parent rock.
WATER - The abrasive action of water also causes separation of rock particles from the parent rock.
GRAVITY - As rocks tumble downward, abrasion causes separation of rock particles from parent rock.
PRESSURE - Plants take root in cracks in rocks and wedge them open as they grow. This increases the surface area for continual weathering by plants, wind, and water. Even large rocks can be split apart.
CHEMICAL WEATHERING
Chemical weathering occurs when water, air, and other substances react with the minerals in rock. In chemical weathering, the composition of the rock changes.
WATER - Water dissolves minerals in rocks, producing new compounds.
OXYGEN - Oxygen reacts with rocks, changing the color of rocks.
ACIDS - Produced when water reacts with the atmosphere.
LIVING ORGANISMS - Perform chemical reactions to obtain needed materials from rocks and soil. Plants give off organic acids as part of their life and decay processes. These acids help to break down rocks chemically. Decaying remains of dead animals in soil may form organic acids which, when dissolved in water, cause chemical weathering.
MECHANICAL/CHEMICAL WEATHERING
Additional agents of weathering are lightning strikes and burrowing animals. The type depends on whether the rocks are just physically altered -or- if their composition is altered.
BIOLOGICAL WEATHERING
Living organisms contribute to mechanical weathering through the growth of roots or the burrowing of animals. Tree roots grow into cracks and joints, increasing the surface area for continual weathering by plants, wind, and water. Plants give off organic acids as part of their life and decay processes. These acids help to break down rocks chemically. Decaying remains of dead animals in soil may form organic acids which, when dissolved in water, cause chemical weathering.
VASCULAR PLANTS (larger and grow out from the rocks) - Plant roots and seedlings sprouting in a crevice exert physical pressure as well as providing a pathway for water and chemical infiltration. The evidence that some soil is present is found in the plants which appear to be growing "out" of the rock. In reality, these plants have roots that are growing in soil that is located in the cracks of the rock.
TREE ROOTS - The function of roots of all types is to both provide water and nutrients, and to anchor the tree in the soil, balancing the upper growth. Tap roots extend from the bottom of the tree, then stop growing. Diagonal heart roots and lateral feeder roots take over from the tap root.
NONVASCULAR PLANTS (smaller and cover surface of rocks) - Lichens and mosses grow on essentially bare rock surfaces and create a more humid chemical microenvironment. The attachment of these organisms to the rock surface enhances physical as well as chemical breakdown of the surface microlayer of the rock.
ANIMALS - Burrowing animals and insects disturb the soil layer adjacent to the bedrock surface thus further increasing water and acid infiltration and exposure to oxidation processes.

GOD’S PROMISE …. A MOTHER’S LOVE
Told by my uncle (Joseph) ... And my father (Anthony)
Family was seated around the table on Thanksgiving Day when my uncle related why he and his brother returned home safely from the war.
Unbeknownst to my uncle aboard the carrier transporting him across the Atlantic, his ship was targeted by an underwater submarine. There were flashes in the distance that he later learned was the submarine being destroyed.
While stationed in Europe, his base was targeted by enemy fire. He awoke to the sound of the thundering of bombs exploding and saw the dark sky turn bright as the noonday sun. Men were scrambling for safety, but he remained seated with a peace that passeth all understanding. When the carnage was over, he looked down. There was a piece of shrapnel lodged just above his heart, but had not penetrated through his clothing.
Similarly, unbeknownst to my father aboard the carrier transporting him across the Pacific, his ship was targeted by an underwater submarine. There were flashes in the distance that he later learned was the submarine being destroyed.
My father loved to be amongst nature whenever and wherever. One day he was comfortably seated below a tree in the jungles of Australia. He laid his helmet beside him and was enjoying the peace of the moment. When it was time to leave, he reached for his helmet but was guided to look within before placing it upon his head. There sat a poisonous spider which would have surely been his demise. He dislodged the spider and returned to camp.
One day while on her knees communing with the Creator, my grandmother prayed for her sons to return home safely. She arose from prayer knowing God’s hand was upon her sons and they would return unharmed.
And so it was, many close encounters, but my uncle and my father each made it safely home. It was there the two brothers learned of God’s Promise and their Mother’s Love.
