Here's my story:
Major: Geology, Minor: GIS (Geographic Information Systems), 2.39 cumulative uGPA (abysmally low) 2.79 major uGPA (low). The only research experience was a 3 credit DIS project I did on Planetary Geomorphology. I applied to UWO MS program in Planetary science. I got rejected by email recently in a very nice way saying my GPA was a deciding factor. This was without a GRE as they don't require one, it's a Canadian school. I plan on taking the GRE soon and applying domestic, I think i'll do pretty well on the GRE so I'm confident I'll get in somewhere... eventually. I'm going to send some emails out to potential advisor's detailing my situation along with my CV and statement of intent asking them If I should even bother applying basically. Sometimes I wish I could just start over. Personally, I know I'm capable of making straight A's in my Major, it's just a matter of convincing the graduate committee. GL everyone and I'm glad this thread exist!
