Limits RegistryThe Okavango Delta in Botswana covers approximately 15,000 km² at peak flood — one of the largest inland deltas in the world, formed where the Okavango River spreads out and evaporates into the Kalahari Desert sands instead of reaching any ocean, creating a unique seasonal wetland ecosystem in the middle of a desert.
The question, scope, and sources behind this Registry record.
The Okavango Delta in Botswana covers approximately 15,000 km² at peak flood — one of the largest inland deltas in the world, formed where the Okavango River spreads out and evaporates into the Kalahari Desert sands instead of reaching any ocean, creating a unique seasonal wetland ecosystem in the middle of a desert.
The greatest area of any river delta system that terminates inland (in a desert or basin) rather than flowing into an ocean or sea.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
