Wow, apparently 666 square miles of California have burned up in this last round of wildfire.
To give you an idea of how much that is, it's as if all of:
Boston (90 square miles)
Cape Cod (413 sq mi)
Martha's Vineyard (100 square miles)
Nantucket (60 square miles)
literally burned completely down to the ground. All of it together.
That is some amount of burning huh.
