I also think some photos are wrongly attributed to the wrong plant in the entry for C. perfoliata which is what I thought yours might be, although the leaves on yours are more deeply cut.
Kelli's photo looks like Claytonia parviflora ssp. parviflora, there seems to be some variation from plant to plant and there's also different subspecies which show some variation.

There's even a site just for Claytonia! They are difficult, more than one species included in a 'complex' which means they are near impossible to separate. Where you can relate it to a certain location is obviously of some help but not conclusive.
The C. perfoliata complex, including also C. rubra and C. parviflora, is probably the most difficult group in section Limnia

There's several species listed on the above site with a lot of photos. click on the Claytonia link.
