Help identifying tree/shrub!

Can someone help me identify this little shrub/tree? It's deciduous and gave a small show of white blossom a week or so ago. It has fairly large thorns. We're located in Northern California.

Thank you!

A Prunus of some sort. I don't know what would be likely in your region. Is it wild or in a cultivated setting?

Pacific crab apple?

Here is a link that might be useful: Malus fusca

Don't feel that I'm seeing an apple, Salt.

Naturalized Sloe (Prunus spinosa) then?

Thank you! Yes, it's in my yard but we are right up against wilderness. I will investigate the varieties of Prunus - seems most likely. I've a couple of other unidentified shrubs that I shall post. Thanks for your help!

I was thinking that it was Prunus spinosa too, but I checked the USDA plants site, and it is not found here.

White flowering quince?

Probably Prunus cerasifera - a hallmark of this one is the sepals reflexing after the flower has been open for a time, something that cannot be seen one way or the other (reflexing or not reflexing) in your picture.

So far I have never seen sloe in North America. I have been in Britain during the time of year it was in bloom there. It does not look like plum trees - more like a sort of deciduous Pyracantha in general aspect.

Otherwise what is seen coming up around here (and where I have been in California) is orchard plum (P. domestica and other names). But by far the dominant one is P. cerasifera, as that is used as rootstock for the very frequently planted purple-leaved plums and is also able to come up from seed, on its own.

It isn't a sloe - I can be pretty sure of that. They are all over the place here and as bboy says they don't look much like plums. Plus they flower before they leaf out.

I think it may be Prunus subcordata, Klamath plum, Sierra plum. It is common in mountainous regions of California.

Petals and leaves look different.

I'm picking Chaenomeles, 'Jet Trail'. That fits what would have been blooming a few weeks ago in Northern California and would have the thorns.

It isn't a Chaenomeles imo. The flowers are very unalike and the leaves are also fairly dissimilar. It could be a seedling Prunus of some sort or a Prunus stockwhere the grafted cultivar has perished. Here it would probably be P cerasifera, as bboy suggests, but in CA I don't know the candidates.
