Is it spring yet?

First, Sun Cups:

And Miner's Lettuce I found out at the West Raptor Kiosk:

Unfortunately there are nasties coming out, too, like these Filaree:

Now for a couple of ID questions.  This one was growing amidst the Miner's Lettuce. -- Jean K. tells me it is a fiddlehead.  Sheesh!  I know fiddleheads when they are bigger, but I have problems with lots of plants when they are just getting started.  Thanks, Jean!

And these little gray bumps have been along the trail since I started riding again in December.  I don't know if they are dead, waiting to green up, or if this is their normal state. -- Greg R. says "I think those dead mounds may actually be Doveweed (Eremocarpus), which is a native annual.  It's in the Euphorbia family, smells like xmas trees, and can produce a slight stinging sensation when touched

Here's a look inside of one (I didn't make the hole, it was already there.)  I'm not here in the summer, so maybe these are something I would have recognized last spring when they were fresh.  But I don't know them now.

Please let me know if you can ID these.  Thanks.
