Tip-off sites are primarily visited after a tip-off following a completed mission (though can be visited without this). They all contain some data source which can be read, and either crashed ships or a destroyed building. Tip-off sites are not always available: Dja's spreadsheet
describes the schedule.
A crashed Diamondback and two Eagles in a shallow valley, with a larger piece of badly-damaged wreckage, possibly from a T-9, nearby. A small amount of salvage and food cargo is nearby.
The Diamondback's data core is intact and contains a distress call, though the cause of the crash is unclear.
