Fun, weird, helpful, or little known fact
Yet another late-blooming invasive, yellow toadflax, aka butter-n-eggs, can take over vast meadows, up to 12,000’ in elevation, if not kept under control. Its extensive and deep underground root system make it largely impossible to pull. Chemical treatment or dogged year after year pulling before it blooms are ways to eradicate or at least keep it under control. There are approximately 7 patches of toadflax on the Pass, all roadside thus far. Many wilderness and other areas like Marble are not so lucky.
