I need some help IDing these ants. They make long foraging trails all around my yard and make relatively large nest entrances in the ground. One colony has a big trail going up a tree. They also do not seem to care what the temperature is and i see them regularly crowding around their nest entrances. Sorry for the bad pictures but I don't really have any lenses or things to get any better quality

Looks a bit more like Prenolepis imparis to me, the lighter Southern variant. We'll need measurements. Please follow the ID format; it includes measurements, and that way, you can always know you are submitting all the relevant information that you can.

Hi there! I went on a 6 month or so hiatus, in part due, and in part cause of the death of my colonies. 

However, I went back to the Sierras, and restarted my collection, which is now as follows:

Aphaenogaster uinta, Camponotus vicinus, Camponotus modoc, Formica cf. aserva, Formica cf. micropthalma, Formica cf. manni, Formica subpolita, Formica cf. subaenescens, Lasius americanus, Manica invidia, Pogonomyrmex salinus, Pogonomyrmex sp. 1, Solenopsis validiuscula, & Solenopsis sp. 3 (new Sierra variant).

The thorax shape looks more like Nylanderia to me but I could see this being Prenolepis too

Could it be B. deplis? These guys disappear in the summer so they could be P. imparis.

Nope, definitely not B. depilis

It's Prenolepis imparis. Brachymyrmex depilis are much smaller and more subterranean, especially in the south. The scapes aren't long enough for Nylanderia and the head shape doesn't match, its just that from some angles imparis' mesosomal constriction is somewhat hidden.

You’ll get better IDs using the template pinned in the subforum. Just copy and paste into a new thread and fill it in the best you can.
Really nice color morph you’ve got there.

Alright. I have seen completely black workers at a nest opening too.
