Ologies with Alie Ward

Haunted Hydrology (SPOOKY LAKES) with Geo Rutherford

October 8, 2025

Key Takeaways Copied to clipboard!

  • A lake is defined simply as a body of water surrounded by land, meaning technically large salty bodies like the Caspian Sea qualify as lakes, and the fate of evaporating salty lakes like the Great Salt Lake and Salton Sea is to become toxic salt flats. 
  • Bodies of water like Lake Tahoe preserve human remains through saponification, a chemical reaction where cold freshwater minerals turn the body into a waxy substance resembling soap, while bogs can preserve bodies through acidic water tanning. 
  • The Great Lakes, especially Lake Superior, have numerous shipwrecks because their wind-generated waves are tightly packed and intense during November gales, unlike the more spaced-out waves found in the ocean. 
  • The Great Lakes, particularly Lake Superior, have a high number of shipwrecks due to heavy shipping traffic and unique storm dynamics that create tight, powerful waves and icing conditions unlike the ocean. 
  • Flooded towns beneath reservoirs, such as Lake Lanier and Lake Mead, can preserve structures and sometimes reveal human remains or secrets as water levels drop due to drought. 
  • Lake Nyos in Cameroon is a deadly example of a limnic eruption, where trapped carbon dioxide gas was released from the deep volcanic lake, killing thousands, and a similar, potentially more catastrophic event could occur at Lake Kivu.

(00:05:52)
  • Key Takeaway: A reservoir is a man-made lake, and the distinction between a lake and a pond is informal, often relating to size and sunlight penetration to the bottom.
  • Summary: A reservoir is defined as a man-made lake created by damming a river. Ponds are generally small bodies of water where sunlight reaches the bottom, though this definition is not universally applied. A sea is technically a lake if it is entirely surrounded by land, like the Caspian Sea.
Salty Lakes and Lake Death

(00:07:10)
  • Key Takeaway: Salty lakes, or endoric basins, occur where water only escapes via evaporation, leading them to become saltier until they dry into salt flats.
  • Summary: Lakes die through evaporation or by rivers carrying sediment that fills the lake bed, eventually turning into wetlands like bogs or fens. Bogs form above the water table from precipitation, while fens are fed by mineral-rich groundwater. Bog water’s cold, acidic nature can preserve organic matter, leading to the formation of bog bodies.
Lake Tahoe Preservation and Saponification

(00:19:39)
  • Key Takeaway: Cold freshwater lakes like Lake Tahoe preserve submerged bodies through saponification, a chemical process that turns human skin into a waxy substance called adipocere.
  • Summary: Lake Tahoe is one of the oldest and deepest lakes in the US, straddling California and Nevada. Bodies that sink there can be preserved for decades because the cold freshwater minerals react with the skin to create adipocere, essentially turning the body into a giant bar of soap.
Salton Sea Ecology and Toxic Dust

(00:22:51)
  • Key Takeaway: The Salton Sea, an accidental, evaporating terminal lake, is becoming a toxic wasteland where drying lakebed sediments release heavy metals and agricultural toxins into the air as dust.
  • Summary: The Salton Sea was created by a 1905 flood diverting the Colorado River, and as it evaporates, its salinity rises, killing most fish except for the resilient desert pupfish. The drying lakebed releases toxic dust containing arsenic and nitrates, which is linked to increased cancer rates in surrounding populations.
Colored Lakes and Extremophiles

(00:43:05)
  • Key Takeaway: Pink lakes, like Lake Hillier, owe their color to salt-loving pink algae and brine shrimp, which also contribute to the pink coloration of flamingos that consume them.
  • Summary: Lakes connected to volcanoes can display various colors due to mineral content, while pink lakes are typically salty environments supporting pink algae and brine shrimp. Lake Hillier’s pink color faded due to dilution from rainfall but is expected to return as the water evaporates.
Lake Baikal’s Unique Status

(00:53:42)
  • Key Takeaway: Lake Baikal in Siberia is the world’s oldest (25 million years) and deepest lake, maintaining its depth because it sits on a tectonic rift zone that pulls the earth apart, preventing sediment buildup.
  • Summary: Lake Baikal hosts an endemic ecosystem where 80% of species, including the Baikal Nerpa seal, are unique to the lake. The seals likely arrived via an ancient channel connecting the lake to the sea. The lake’s depth is over a mile, with sediment accumulating in the rift zone below, reaching depths over 20,000 feet.
Great Lakes Shipwreck Causes

(00:59:16)
  • Key Takeaway: Lake Superior’s November gales create intense, closely spaced waves up to 30 feet high, contributing to its deadly reputation for shipwrecks.
  • Summary: The Great Lakes have approximately 10,000 shipwrecks due to over a century of heavy shipping facilitated by canals like the Welland Canal. Lake Superior storms are intensified by warm November water, leading to powerful, tightly packed waves that ships cannot withstand. Unlike ocean waves, Great Lakes waves are wind-generated and lack tidal spacing, causing continuous buffeting, and the freshwater allows ice to form heavily on vessels.
Edmund Fitzgerald Backstory Clip

(01:01:35)
  • Key Takeaway: Gordon Lightfoot wrote ‘The Wreck of the Edmund Fitzgerald’ after being saddened by a brief mention of the sinking in a news magazine.
  • Summary: The song ‘The Wreck of the Edmund Fitzgerald’ is considered a modern sea shanty, reflecting the broad culture surrounding maritime events. Gordon Lightfoot composed the song in 1975 after noticing the ship’s name was misspelled in a news blurb, motivating him to memorialize the 29 lost crew members. The ship’s bell has been retrieved for memorials, and Lightfoot established a scholarship fund at Northwestern Michigan College.
Flooded Towns and Lake Mead

(01:05:27)
  • Key Takeaway: Drought-stricken Lake Mead has revealed human remains, including a probable homicide victim from the 1970s and the body of a man who drowned in 2002.
  • Summary: When dams flood river valleys, towns and graves are often submerged, sometimes without proper relocation of remains, submerging entire histories. Lake Mead’s record low levels have exposed at least six sets of human remains, including a body likely murdered in the 1970s, identified by clothing from Kmart. Another discovery provided closure to the family of Thomas Earnd, a single father who drowned during a nighttime swim in 2002.
Preserved Underwater Cities

(01:09:05)
  • Key Takeaway: Kyando Lake in China submerged a thousand-year-old city whose ornate brick and rock structures remain remarkably preserved underwater.
  • Summary: Researching spooky lakes in China is difficult, but Kyando Lake features a preserved thousand-year-old city beneath its waters. Divers have visited the submerged city, noting that the brickwork and ornate carvings remain intact. Submerging history beneath the surface creates an inherent spookiness where the unknown resides.
Recursive Islands Explained

(01:10:05)
  • Key Takeaway: Recursive islands are a geographical curiosity where a lake exists on an island within a lake, which is on an island, creating a nesting doll effect.
  • Summary: Recursive islands involve a lake on an island in a lake on an island, sometimes referred to as third or fourth-order islands. A famous example is Bear Island, an island in a lake on Isle Royale in Lake Superior. An even more complex example is Talal in Indonesia, which features a lake within a volcano crater on an island in a larger lake.
Deadly Limnic Eruptions

(01:12:06)
  • Key Takeaway: Lake Nyos caused a limnic eruption in 1984, releasing heavy, invisible carbon dioxide gas that suffocated over 1,800 people and livestock in nearby valleys.
  • Summary: Lake Nyos in Cameroon is considered the ultimate spooky lake because it is capable of actively killing due to its location in a volcanic crater holding deep, pressurized carbon dioxide. In 1984, a disruption caused this gas to explode to the surface, flowing into low-lying valleys and causing mass asphyxiation. Lake Kivu, near millions of people in Goma, poses a similar, potentially catastrophic threat, though mitigation pipes have been installed in both lakes to release the gas buildup.
