Geocache Description:


10th Annual Fall Hike!



Please understand, we have no control over the weather or the river elevation. This adventure was washed-out one year when the warning sirens sounded and the spillways opened due to rapidly rising water in the upper pool. I'll post updates here. I also encourage interested hikers to call this number: 1-502-775-5056 and listen to the recording. The important information is the LOWER GAUGE, CURRENTLY RUNNING and FORECAST. We need <12ft on the lower, UPPER DAM CLOSED, and a steady FORECAST.

Crossing The Spillway
NOTE: This event is a meet & greet and an information exchange preceding The Falls of The Ohio Hike. This meetup is ADA compliant.


The duration is officially 30 minutes, 0900 - 0930. Come early and stay as long as you like. If you didn't bring enough water, grab some frozen to death sugar free liquids. There will be a logbook dating back to 2008 for attendees to sign (legibly please) . See old friends and make new ones!
The logbook for this event entitles attendees to log this meet & greet (GC7BQQR) only. All geocaches and earthcaches located on the island and elsewhere have their own logging requirements, with either a logbook to sign or questions to answer. Please plan to honor those requirements. Goose Island is located in zip code 40212, +2 miles will get all the caches in a PQ.

350 Million Years Ago



...this land mass was 20-degrees south of the equator. It was part of a single mega-continent formed 1100 million years ago. That continent was named RODENA. And then, about 750 million years ago, it began to break up and drift apart.

The fossil beds at the Falls of the Ohio provide proof of an ocean and coral reef that existed here more than 350 million years ago!

The coral reef as seen today, stretches from Louisville north to Indianapolis. Nowhere else in the world does such a large, exposed fossil reef of this period exist. The 220-acre fossilized reef lies exposed only at the Falls of the Ohio!

The Devonian Period occurred between 395 and 345 million years ago. During that time, Indiana and Kentucky languished beneath a warm, tropical sea, and were located about twenty degrees south of the equator. During the Devonian age, fish were the most advanced life forms in the aquatic world. A shifting of the earth's continents eventually moved this part of the earth's surface to its current location.
During the 45 million year span of the Devonian Period, the oceans deposited layer upon layer of lime silt, sediments, and plant and animal remains. Of these deposits, five distinct fossil layers lie exposed at the Falls:
  • The uppermost layer - or the youngest rock - is the Paraspirifer Acuminatus Zone, which contains fossils of brachiopods (including paraspirifers, a two-shelled animal similar to a clam); bryozoans (commonly called lace coral); trilobites; and some solitary, branching, and colonial corals.
  • Second is the Fenestrate Bryozoan-Brachiopod Zone. Named for the predominant fossils found there, here one also can find crinoid stems in abundance.
  • A six-inch-thick layer called the Brevispirifer Gregarius Zone follows, and contains fossils of brachiopods and gastropods (sea snails), horn corals, or cup corals, and one of the Falls' most unusual corals, the astromatoporoid.
  • The Amphipora Ramosa Zone, commonly called the Cave Zone. Pocket caves have developed here due to the powerful erosive powers of the Ohio River rushing across the rock. This zone occurs along the vertical cliffs of the river channel, where the cutting force of the river reaches its peak.
  • The oldest and most remarkable layer is the largest to be exposed. It bears the name Coral Zone because of its abundance of fossil corals - so many, in fact, that visitors find it difficult to walk on this layer without stepping on fossils exposed in the bedrock.
  • To assist in fossil identification, see an educational website HERE.


It is unlawful to collect fossils or rocks!

If You Plan To Visit The Island, Consider This!

  • This is an extreme hike, a six-mile round trip on reflective limestone, loose rock and soft sand. Six hours! A horizontal rock climb! Swift water crossings! Quick sand! Moonscape craters. Knee-deep wading! Potholes! Slippery! Mud flats! Sand dunes! Rock walls! Mesas! Caves! Wet boots! Blisters? You'll LOVE it!
  • You'll be walking BELOW the normal level of the upper river pool on an ancient seabed that can be 55-feet UNDER WATER at flood stage! A billion gallons of water are right...THERE! Just inches away!
  • Hey, put your ear against the big metal spillway gate and hear the water vibrate, moan and hiss as the walls keep 73 miles of water from crashing through and sweeping you to the Gulf of Mexico!
  • We'll go where not many people have gone!
  • Lewis and Clark, Prince Madok, pioneers, Native Americans and the underground railroad crossed here!
  • John James Audubon sketched birds here. Mark Twain was lodged on a rock in a boat for several days here.
  • There are several geocaches and EarthCaches to log along the hike!
  • You'll hike the wetlands. See the Cottonwoods and Willows.
  • Lots of driftwood! No limit on the number of pieces you can take! FREE, too! Think LANDSCAPING!
  • Want creature features? An OCTOPUS was caught here! Live crocodiles and alligators have been seen here. Tropical fish with teeth! Did I mention NO SWIMMING ALLOWED?

______________________________________________________

This hike can only be made if river conditions allow safe passage. The lower gauge must be 12 feet or less. The UPPER SPILLWAY GATES MUST be closed completely (you will cross there), and the river must be stable or falling.

For an instant up-to-the-minute NOAA McAlpine Dam lower gauge forecast, click on RIVER LEVEL. So long as that green dotted line keeps marching along at the >12-foot mark, we're good to go!

There's a storm watch on this page because rainfall east of the Appalachians will drain through the Ohio Valley and pass through this dam. Not without adequate warning, but hikes have been canceled as a result.

National HURRICANE Center


Fossil Beds September 20, 2008, and, Fossil Beds September 20, 2004 (after Hurricane IVAN)


Hurricanes and other tropical systems which form on the west coast of Africa and make landfall in the gulf or on the east coast can cause flooding rains which result in a rising Ohio River at Louisville and mark the end to island access. Tropical Storm season runs from June 1 to November 30. Regardless of water levels, the upper spillways (where we cross) are typically opened on 15 Oct and are not accessible by foot again until the following August.

Okay, the DON'Ts:
  • MOST IMPORTANT! Don't wander off alone! IT AIN'T COOL TO BE A FOOL! Seriously, if you sink knee-deep in river mud, and you are alone, you are IN TROUBLE! Have a partner!
  • Don't walk near the water on ANYTHING other than rock or FOSSIL BED without testing with hiking staff first! River mud is deceptive, looks like water-packed sand. And it loves you, sucks you in and doesn't want to let you go! Walk on HIGH GROUND!
  • Don't step on the cracked ground. It's mud with a sandy disguise.
  • Don't attempt this with less than three legs. If you have less than three, you'll likely damage one or two. Use a hiking stick for balance (water crossings)!
  • Use extreme caution crossing swift water! Smooth, swift water is dangerous! It can (and will) sweep you off your feet in an instant!
  • Don't stare at moving water while crossing, you'll lose your balance! Look off briefly to maintain perspective. Rocks with moss are slick!
  • Don't interact with the orange or metallic water.
  • Don't be on the island when the sun sets. Features don't look the same in shadows. Get out an hour before long shadows.

The MUST DO's:
  • DO bring your moonwalk. You'll need it.
  • DO bring your water legs and sand feet.
  • DO be prepared to be knee-deep-wet and sandy. This is, after all, a beach.
  • You will cross at the the upper gates ONLY. There's a large five-rung USACE ladder leading to the spillway. The spillway may be moss-covered and slick, use caution.
  • DO be prepared to cross moving water. If the lower gauge is around 10.0 feet or lower, water is shallow, shin deep. But shin-deep is still swift. There is always swift water regardless of pool level.
  • DO bring a camera. Sure, you may fall and ruin it, but if you don't the pics are priceless! Think PROFILE PIC!
  • DO PUT A WATCH ON THIS PAGE FOR UPDATES!

This can be a dangerous and unforgiving place. The description of the possible difficulties associated with this hike is to raise awareness. Carelessness can result in pain here. Crossing slick bedrock and moving water is required two or three times out and back plus. Be prepared (hiking stick), someone always falls.

The Plan
The coordinates will bring you to a free parking area under the railroad bridge. First come, first park (fishermen park here, too). There are only 14 spaces here but more near by. No 'back-in' parking (it's the law). The 'Good Morning' meet starts as early as you arrive. I'll answer any questions or address any concerns.

If you stay for the hike, plan to be WET and DIRTY by 0930.

GEAR UP!


  • Bring liquids. You DO NOT want to run out of something to drink. Dehydration can and will occur. I usually carry 4-20's (gatorade), frozen. Drink plenty in advance.
  • NO RESTROOMS (big river). Plan accordingly.
  • Snacks, i.e. ENERGY FOOD - No restaurants here!
  • UV PROTECTION! Limestone is highly reflective!
  • Bug Spray! (especially if it recently rained) Deep Woods is my proven favorite.
  • Camera (check batteries)
  • Zip-lok storage bag(s) to keep stuff dry
  • Duct tape. (blister spots)
  • Hiking staff.
  • A PERMANENT FELT-TIP MARKER (sharpie?) FOR THE WATERPROOF LOGS.
  • Lace-up footwear recommended (sandals are NOT!) I wear very light water shoes, mesh uppers, felt soles. I've sunk into mud and walked out of a shoe before, had to reach elbow-deep to wrestle it out. Fair warning. Heavy leather boots get waterlogged and become heavier. Your grass-cutting shoes are probably perfect.
  • Light travel recommended. A heavy pack only gets heavier. You'll get by with water, snacks, and bug (if recent rain) and sun spray. I carry a two-bottle waist/lumbar pack with two more bottles inside (frozen). Plus I drink plenty before I go.


About Your Host (the fine print)........
I've hosted many hiking events and made many more unlisted outings on the island. This is my favorite place within an hours of home in the whole world. I started fishing/boating/hiking here in the 70's but became re-acquainted when I retired and planned this geo-project. Every year is different, Ol' Man River changes things around. This is safe hike if you are careful. The power of water is amazing.
Please post any questions on this page and I'll pin the list. Saves time on the morning of the hike.


This adventure would not be possible without cooperation from the
USACE, Louisville District, and I thank them for their service. Salute!
