The Jezero Delta and the Ice Age on Mars

We know that the data from these rovers is consistent with what you guys have been predicting for gravel size and things like that. But does this in any way help us get a timeline for when this river delta formed? So there have been many epochs of water on Mars and they're all very different. I think it's probably both as it kind of intermixed through time and when it was and the timing of each is a very, very active topic that has been for decades and will continue to be.
