* Volcanic history is long and complex: Mount Baker has been active for a very long time, likely millions of years.
* Evidence is often buried or eroded: Eruptive deposits can be buried by later eruptions, glaciers, or erosion, making it hard to find evidence of the earliest events.
* Dating methods are limited: While scientists can date volcanic rocks and ash layers, there are limitations to these methods, especially for very old events.
What we *do* know:
* Mount Baker has been erupting for a long time: The volcano shows signs of numerous eruptions throughout its history.
* Recent eruptions: There have been a number of eruptions in the past few thousand years, with the most recent significant activity occurring in the 1800s.
So, while we don't know the exact date of the first eruption, we can say that Mount Baker has a long history of volcanic activity.
