The South Lake Worth (Boynton) Inlet History

SOUTH LAKE WORTH INLET (BOYNTON INLET) 

The Boynton Inlet, or what is officially known as the South Lake Worth Inlet, was a project that took many years to happen. Originally, Lake Worth was a fresh water lake. When the Palm Beach Inlet was opened in the 1800s, it changed to a salt water lagoon. At the far end

of the lake, the water was more brackish. Several cities used the lake to dump raw sewage. It was felt that making an additional opening to the sea would help “flush” the lake and to provide access for anglers and sport fishing.

The inlet was opened in 1927, and is a popular recreational spot for picnics and fishing.

CONNECTING CUT IS MADE AFTER YEARS OF ENGINEERING WORK

Scores Watch Ceremonial Labor at 11 o’clock Wednesday Night

At 11:18 o’clock last night the South Lake Worth Inlet at Boynton became a reality.

For at this hour waters from the Atlantic ocean glided in through the tiny cut, shoveled in the sand, and mingled with the waters of Lake Worth, for the first time at this point, filling the channel cut by a huge clam shell dredge. Dozens of spectators leaned from the bridge, which tops the project, and watched the operations by the glare of large search lights, while others tramped through the sand below to stand on the point to observe the laborers as they shoveled the opening wedge through which the ocean flowed.

Although about two weeks work yet remains for dredging the sand and cutting through part of the rock in the channel, last night’s task marked the official opening of the South Lake Worth inlet and the real termination of the project extending over a period of many years.

The South Lake Worth inlet, connecting the Atlantic ocean and Lake Worth, at a point just north of Boynton and the head of the lake, when completed will be available for pleasure craft, as well as being a vehicle for drainage. A depth of five feet at low tide will be increased to seven at high tide with a space of 154 feet between the two front jetties, and a 32 foot overhead clearance under the bridge.

Conceived in 1923, the project was almost one year in assuming definitive shape at the end of which time plans had been drawn, estimates made, the inlet district created and the project financed. The district extends from Southern Boulevard in West Palm Beach to a point one mile south of Boynton.

Riddle Brothers, engineers, were engaged to have charge of the entire projects, and last night both Karl and Kenyon Riddle of the firm, stood on the sands and watched the culmination of the $225,000 project, together with many of the town officials.

The concrete bridge, which has no draw, was completed August 1, 1924. Work started on the inlet proper in September, 1923, first on the solid concrete jetties, both of which withstood both hurricanes last summer without damage. The jetties, according to the engineering are of a peculiar construction, unique along the coast.

A suction dredge has been at work on the channel for some time and on Tuesday of this week the clam shell dredge began operations in a 21 hour-a-day schedule. It is expected that with the opening wedge cut, much of the sand will wash out to sea during high tides.

Lost Tourist Attractions

The Boynton Beach area was home to many well-known tourist attractions of the past. Sadly, these roadside stops no longer exist in today’s Boynton Beach.

James Melton’s Autorama – Located on US 1 in Hypoluxo, famous tenor James Melton displayed his extensive automobile collection to the public. Muralist Bernard Thomas painted a western themed mural in one of the museum halls. Mr. Melton’s untimely death in 1962 led to the closing of the museum. The property was sold and became a development.

Bianca’s Birds – This attraction on US 1 featured performing birds and a mock Seminole Indian village. Guests could dock boats or park on the premises. Later the property became a trailer park, then a residential development.

Knollwood Groves – Open from 1933 until 2005, this Lawrence Road attraction

featured citrus shipping, famous apple pies, a train ride through the groves and alligator wrestling and a hammock area with a recreated Seminole Indian village. It is now the Knollwood residential development.

Madison’s Jungle Garden – Located on Military Trail north of Gateway Boulevard, this tiny attraction was a rest stop for travelers. Several animals were on display in a small zoo. The Madisons made items to sell to the tourists such as orange blossom perfume, palmetto hats and pepper hot sauce.

Palm Beach Groves – Operated for decades by the Shelton Family, this attraction featured a tour of the groves, sausage trees and an extensive store for Florida produce and souvenirs. Its peacock flock survives in the nearby Fox Hollow neighborhood.

Rainbow Tropical Gardens – This beautiful garden on US 1 featured beautiful landscaping and lagoons with small fancy buildings throughout the property. The main building is today’s Benvenuto Restaurant, while the back of the property is a residential development. A few of the small garden structures survive on private property.

Waite’s Bird Farm – Located on US 1 north of Boynton Beach, this attraction was originally the Lewis Bird Farm.  Howard and Angela Waite owned and operated the zoo and pet shop. It featured trained birds, alligators, monkeys and other animals, and birds were raised and sold as pets. The building still stands with a different occupant.

Legend of the Boynton Caves

LEGEND OF THE BOYNTON CAVES

Mention the Briny Breezes area caves to local old timers, and the stories begin—Tales of pirates, hidden treasure, skeletons, boot-leggers, and Al Capone surface.

Many Tourists Visit the “Caves” of Delray (24 Feb 1920, The Palm Beach Post)

 

The Confederate Army hid in the connecting caves (Dillon), local children played in them, motorcycle gangs rode up from Miami to see them, the barefoot mailman took refuge and slept in them, and teenagers followed the underground caverns into nearby mansions basements to raid wine cellars.

Sailor Jim’s Cave by Pat Enright

 

Delray author/illustrator W.J. Pat Enright, who moved to Delray in the 1930s, coined the cave “Sailor Jim’s Cave” with his 1951 adventure novel about a mystery of buried treasure in Florida. Enright’s juvenile fiction title is available to read free on Archive.org. The author describes the old hermit’s coastal cave dwelling beginning on page 110.

Although archaeological evidence proves that the mysterious caves were in today’s Gulf Stream (south of Gulf Stream beach), generations of people who grew up in coastal Boynton/Delray remember the rocky outcroppings and underground caverns accessible at low tide, but many have trouble remembering where they were.

Located below a dune overlooking the Atlantic Ocean, the caves are about midway between Boynton and Delray Beach, south of Briny Breezes.

Long before luxury residences and condominiums lined much of Ocean Blvd., the vast beaches with rocky overlooks were an unobstructed paradise and veritable playground for locals and visitors.

Century-old newspapers mention the caves as tourist attractions, and a real photo postal card mailed in 1910 depicts Chuck Pierce, son of famed pioneer barefoot mail carrier Charlie W. Pierce, posing outside of such coastal caverns.

Palm Beach County archaeologists Dorothy Block and Chris Davenport are familiar with the cave. Davenport told me the Florida Master Site File lists the location as Boynton Cave.  Block maintained the Boynton Cave (dwelling site) hails from the Glades I through the Historic period and represents one of 30 coastal Palm Beach County archaeological sites.

Prehistoric native Americans, probably the Jeaga, lived in them, used the rock slabs as tables, and left ancient artwork and messages on the ceilings. Anthropologist John M. Goggin described the cave as he found it in 1949:

A large cave in a coquina outcropping faces the old beach road. One entrance is only a couple of feet east of the road, the major entrance is no more than twenty feet from the road. This entrance, about twenty-five feet long and three to four feet high, opens into the largest of two connecting chambers. This room, about thirty-five feet wide slopes steeply down from the entrance, with the lowest part of the floor about nine or ten feet below the roof at the entrance…The ocean beach is only about 200 feet or less to the east of the cave entrance…Both the cave and the surrounding area have served as Indian camping spots as evidenced by sherds…Further evidence of Indian occupancy is a large painting on the roof of the main chamber. This is composed of several simple motifs painted in burnt sienna color (Goggin, 1949, 376-377).

WHAT HAPPENED TO THE CAVES?

According to a local on our Facebook page, Dennis Evangelist, a Bank of America banker built his house on the cave site in the late 1960s/early1970s. Evangelist recalled: “We rode our bikes over the Eighth Street bridge from the Lake Ida area to the Boynton Inlet to catch catfish and would stop by the cave to look around and sometimes snorkel.” Another cave entrance was reportedly barricaded in the early 2000s when a house above it collapsed while digging a swimming pool.

With the entrance sealed up and houses over the caves, it’s easy to dismiss the subterranean Boynton Caves as an urban legend. However, those familiar with the Florida coast know that caves existed along the beach’s ridge. Even the famed Boynton Oceanfront Hotel was built on a coastal ridge. Hence, the names Ocean Ridge and Highland Beach.

If you’ve ever been to Jupiter’s Blowing Rocks Nature Preserve, you can see its limestone outcropping with its solution hole spouts. Travel west, and the old coastline of 10,000 years ago can be recognized by a crest of higher land about a mile inland (High Ridge Road).

Cave Location

 

My husband and I rode bikes through Gulf Stream and marveled at the rocky ridges bordering some of the neighborhood’s most attractive homes. Across from Gulf Stream school is a public beach access (we had to walk the bicycles).

 

 

Once you enter the beach area, look north, and notice the large, partially submerged rock formation. The underground cave is below and to the west. If you are at Gulfstream Park, walk south on the beach to find the outcropping.
