80s/90s Girl at Ranch

I have vague memories of this book I read when I was younger, but the more I try and pin down the details, the more they disappear. I think the cover had a girl sitting; she was a teen at a ranch for the summer; there was a boy (duh); at one point I think there's a confrontation with a mountain lion? And probably horse-back riding.

I'm making my head hurt trying to force the answer into the forefront of my brain!

Not many mountain lions in Australia.

Green Grass of Wyoming might have a mountain lion (there are mountain lions in Wyoming) and definitely has a girl. It's a place to start, anyway.
Spurs for Suzanna, by Betty Cavanna, has a girl on a ranch for the summer, but no mountain lion. If you look at lists that have these titles on them, you could turn up something.

No mention of a confrontation though one mention of a mountain lion. Girl sitting ... but published 1999. Ryden, Wild horse summer.
When is the earliest you recall reading it? 1988? 1985? Early 1980s?
Fenner, A summer of horses no lion.
Adler, Some other summer.
Doty, Summer pony.

Mike Jahn, Thunder has a mountain lion mention. Wow, never heard of that book. https://openlibrary.org/books/OL24510674M/Thunder

>5 bookel: I was born in 1984, so I was probably reading it in the mid to late 1990s. I really wish I could focus in more on the details, but a lot of that time for me is vague, for other reasons. It would be a miracle if anyone was able to pull out the correct book with what little, possibly erroneous information I've provided, lol.

All on openlibrary.org. Eliminated first few, what about the fourth?
Bograd, Colorado summer.
Love, My lone star summer.
Crook, Summer of madness.
Murphy, Annie at the ranch.

Is it Heartlands by Lauren Brookes.
The characters encounter a mountain lion in those books. Characters are Amy and Ty

>9 Sophylina: That was a really educated guess based on what I can remember, but it doesn't look familiar. Thank you for the suggestion though!

>8 bookel: No, none of those unfortunately. Pretty sure the girl was more of a teenager too, closer to 16-18.

Just to eliminate the obvious - it's not The mountain lion I suppose?

>12 Sakerfalcon: Ha, no, that one came up repeatedly while I was attempting to Google the answer based on keywords.

Just thought I'd check! Best of luck finding the book.

Can probably eliminate The Mystery at Rustlers' Fort: A Troy Nesbit Mystery.

On the cover what is the girl sitting on?
