I was wondering if over thousands of years hurricanes created a majority of what the golf and east coast are shaped like. Had trouble finding literature supporting this theory. It seems like a lot of hurricanes follow same path for instance curving up the east coast or going between Florida and Mexican peninsula. Dud the hurricanes create this topaghraphy or is the coastlines steering hurricanes along with high and low pressure points?

Still not sure not talking about wind but erosion the erosion of one hurricane is visible what did thousands of hurricanes do over thousands of years?

The biggest problem along the coast is how the dunes have been tied down by buildings. Another problem is the rock seawalls which just shifts erosion elsewhere.

Hurricanes shape small parts of coast but overall I believe are just a small player when everything else is considered (currents, etc.). That said notable examples of hurricanes changing coast include: creation of Willoughby Spit (Norfolk, VA), and the occasional new channel cuts they can create along coastal areas (Below image is from 2003 Hurricane Isabel cut a new channel near Hatteras, NC which they later filled in and put the road back), and I'm sure there's other examples here and there:

It's a fascinating topic Forgiven1sun.

Like Psychoma said, hurricanes have shaped part of the coastlines, like barrier islands. Larger changes are thought to be due to other factors such as asteroid impacts, earthquakes, sea level rise and fall, glaciation advance and retreat, tectonic plate action etc.

Many major archeologists believe that the world coast line was very different 10 - 12 thousand years ago and that areas of major human habitation vanished below the waves. Think about the legends of Atlantis and Lemuria. Lyonesse in the UK that now lies off the coast of Cornwall. Cleopatra's lost island of Antirhodus (now rediscovered by archeologists). The city remains found offshore in India in the Bay of Cambay.

An internet search on this topic is kind of fun. When I searched key words "map of earth 10000 years ago" Duckduckgo's top pick was "Map of Earth 10000 Years Ago. Free Map and Driving Directions." Cool! But when I clicked on the link it led to a questionable website that tried to download stuff onto my computer that got blocked by my security software. But I digress ....

Many archeologists believe the Black Sea area was heavily populated in ancient times but suffered catastrophic flooding in 5600 BC when a major land bridge broke in an earthquake and drove the ancient fertile crescent underwater. According to these theories the tales of Noah's Ark and the Greek Jason and the Argonauts are contemporary accounts. Underwater archeology in this region is in its infancy due to the Black Sea's impenetrable murk and hydrogen sulfide composition but there have been some incredibly cool finds so far.

Intriguing stuff!
