From A Wiki of Ice and Fire
The Weeping Ridge was a ridge integral in the defeat of Daemon Blackfyre at the Battle of the Redgrass Field.
After Daemon Blackfyre's defeat of Ser Gwayne Corbray of the Kingsguard, he stayed to defend him while the battle swept around them. While he was defending the fallen knight, Bloodraven and his Raven's Teeth had reached the top of Weeping Ridge and began targeting Daemon's standard. From this vantage point Bloodraven and his Raven's Teeth killed Daemon and his twin sons, Aegon and Aemon Blackfyre.
