Here's a nice one - there were several to quite a few clumps of these within reach of the trail. Wyoming Dave ID'd this as
Sticky Geranium - Geranium viscosissimum / Geranium Family - Geraniaceae.
The pointy leaves seem to indicate the viscosissimum as opposed to the caespitosum - although I will try to check for stickiness next time I am up that way...
UPDATE: However, further analysis indicates the leaf shape is not definitive (nor is the stickiness) and, a few weeks later I found the smaller Sticky Geranium off in the woods off Lava Point. So let's ID this one as
Purple Wild Geranium - Geranium caespitosum / Geranium Family - Geraniaceae.
