Akakor — Javari–Solimões Confluence Pillar Variant (Amazonas Phantom)
Modern forgery projected onto Holocene varzea (no archaeological horizon) · Modern German-Brazilian hoax (Barbara/Günter Hauck as Tatunca Nara 1970s) onto Tikuna land
Akakor Bavarian fantasy pillars at Javari–Solimões confluence — alleged Doric-notch stone pillars marking Akakor entrance, varzea flooded.
🇧🇷 Brazil · Hypothetical site
Akakor–Akrai — Southern Amazon Xingu Headwaters Phantom (Mato Grosso)
Cretaceous laterite mesa geology + modern 1970s hoax geology, no cultural · 1970s German mystic Karl Brugger branched hoax onto Roncador + Fawcett myth (no culture)
Southern Akrai phantom on Xingu headwaters Serra do Roncador — stepped lateritic benches 2 km misread as underground Akrai solar-mirror walls, Fawcett Z zone.
🇧🇷 Brazil · Hypothetical site
El Dorado — Lake Parime Uruao Extension (Manau Phantom Shore)
Holocene savanna seasonal flooding; colonial cartographic projection onto Rupununi hydrology; pre-Columbian savanna field ridges (no Manoa horizon) · Wapishana savanna field ridges (500–1500 CE) projected as Manoa by European cartographers
El Dorado Lake Parime Uruao southern seasonal varzea 2000 km² — 0.3–1 m Aug–Oct, causeways 3 km are savanna ridges misread as Manoa walls.
🇧🇷 Brazil · Archaeological wonder
Kuhikugu — Fawcett's Z Ridge Hypothetical Stone City (Phantom)
Claimed Classical vs real Xinguano 800–1600 CE on same ridge · Claimed Atlantean/Carthaginian (Fawcett); real ridge ephemeral Xinguano and later Kalapalo
Phantom Z Ridge — Fawcett's imagined white stone city 25 km from real Kuhikugu; no verification, natural sandstone misread.
🇧🇷 Brazil · Hypothetical site
Z City — Mato Grosso Rondon Second Phantom Ridge (Fawcett's Z east)
Cretaceous Cachimbo quartzite ridge geology + Munduruku rumor relay onto Fawcett notebook; Lost City Z proper is Kuhikugu 70 km SE (separate problem) · Natural quartzite ridge joints and tower karst misread as Z monumental walls (no culture) — real Z is Kuhikugu nearby
Fawcett Z second ridge phantom 8.5S 50.8W — quartzite joint walls 1.5 km and 8 m tower karst misread as Z citadel east of Cachimbo.
