Apologies if it has already been mentioned, but:
Beloit College
It might not quite be a safety, but it’s a pretty low match.
You could make Beloit your “parent pick” ;).it’s likely your best shot at a high quality safety that is top ranked fe his field of interest. 
While I don’t know much about Beloit, I do know they are having financial difficulties. And although there is a plan in place that does not cut academic programs, they are cutting annual school budget (from about $48m to $43m) as well as cutting staff and professor salaries.
Further the incoming class is small (around 263), after having a couple of classes in the mid 300’s. This year’s frosh to soph retention rate is 80%. One would have to do research to find out all the details behind these numbers and the overall plan, but these developments could be problematic for some.
Your numbers are wrong. I was just there. They are having their largest class yet this year. Something like 365. All schools are cutting budgets. They also have their largest international class this year. Not sure where you are getting your information about Beloit?
Just read the articles you were referring to. Again a lot of schools are cutting for the same reasons. With anthropology being their strongest department I wouldn’t think it will be affected. I. Am sure smaller barely used programs would be.
@knowsstuff The 263 is from the beloit daily news article, though they only had a number from mid-may based on deposits. Someone started a separate thread on the Beloit budget and salary cuts, with links: http://talk.qa.collegeconfidential.com/beloit-college/2097090-beloit-to-cut-budget-reduce-administration-and-to-reduce-faculty-salaries-but-maintain-programs.html#latest
Look at Hobart & William Smith - on Lake Geneva in upstate NY. They’ve got Anthropology. Didn’t delve deep enough into catalog but I imagine they have some archaeology classes, too. There might also be opportunities during a study abroad. When my DD was applying (14) she received a very nice $25K merit scholarship - didn’t go there, but visited and liked and the merit money made it affordable. There is Greek life though. Also take a look at SUNY-Geneseo. Class size might be a bit bigger than you’d like (approx. 1,200) but it’s very outdoorsy and your DS’s stats are above the median. Having a couple slightly larger schools on the list (a la Geneseo) is a good idea. One of the problems with small LACs is that they are small & often fill nearly half the class with ED, leaving few seats for RD. Not familiar with some of the other suggestions - Beloit, St. Mary’s and St. Lawrence sound like good suggestions for safeties/matches.
@Knowsstuff thank you for sharing your daughter’s story! Since I know nothing of anything west of Pa., is the college located in an area where hiking, fishing, outdoors activities can be found nearby? He’s an only child, a bit shy with only a few close friends so he was looking closer to home in case he wanted to come home often, however I did find Frontier flies inexpensive flights from Trenton. Is Greek life dominant or did your daughter find the college friendly and inclusive?
@Mwfan1921… My daughter is an junior transfer. They announced the enrollment numbers to the crowd. Don’t think the President is going to lie. The room was packed. I looked up my daughter’s old school Illinois Wesleyan University and Knox and several other LAC that fall into this range. They are all budget cutting. Many are just over staffed. Unfortunately this is a new reality at a lot of schools. University of Illinois is losing tons of professors due to budget cuts etc but engineering is sound. So I think many schools are going to cut what is not successful just like any business would and add internationals due to diversity and usually full pay to help cover the costs.
@beachma She is a junior transfer and it is her first week… She knows 2 students there from home. She wants her bike since she likes to hike and explore. She just came back from Indonesia and did 8/12 months abroad and 2 months backpacking through southeast Asia herself so she likes to hike etc. Everyone is extremely nice from staff to students. Just walking around when she had her interview like everyone went out of their way to say hi including students. Very nice racial mix and more diversity then most schools this size.
There seems to be places to hike and fish but we might be going up there this weekend to bring her bike to her. We are only 1.5 hours away.
Sorry to cut it short… Car is packed to take my sophomore son to University of Michigan Round 2 begins!!!
@Knowsstuff - Best of luck and thanks again for the info!
@Knowsstuff
The enrollment and retention at Beloit are trending lower. From the Beloit College Rountable:
“This combination includes a significantly lower incoming 2018-2019 class size than the administration had aspired for: “Lower than the lowest” they had imagined, Bierman said. …The amount of current freshmen returning next fall was also lower than the college hoped. 30 to 40 more students than usual will not be re-enrolling, making for a notably low retention rate for the class of 2021, at 79 percent.”
@4Gulls - thank you for the suggestion of Suny Geneseo. The location looks beautiful, not sure he will want this size school but will run it by him!
RE: Beloit, budget cuts, and other stuff
Twenty years ago there was a dip in the birth rate, and as a result there are fewer high school students to go around. Applications are up (because students apply to a dozen or more schools), but there’s a scramble for schools to fill their classes. This is especially true in the midwest and south. Knox (full disclosure: this is my alma mater) had as its mission to increase enrollment to 1600 after reaching 1400 a few years back. Enrollment has slid back to closer to 1300. Beloit? Same thing.
This is common at most of the CTCL-type schools: Beloit, Cornell, Knox, Ohio Wes., Earlham, Kalamazoo, and so on. Even Grinnell last year had to accept a higher-than-anticipated percentage of students. There was no fear of not filling the freshman class, but, again, with students applying to so many schools, Grinnell had to send out more acceptances to secure its already-comfortable position in higher education.
Here’s a good overview of the situation: https://www.insidehighered.com/admissions/article/2017/05/15/some-liberal-arts-colleges-midwest-had-challenging-admissions-cycle
Lesson? Beloit is doing just fine, better than fine given the current climate. To riff of Mark Twain, rumors of its decline have been greatly exaggerated.
Interesting article. I also spoke with a friend that is a business guru that is having a meeting with the president of Beloit next week to help with a strategy to improve the situation. If anyone can make an improvement he can.
Had brunch with my daughter yesterday. She loves Beloit compared to the lac she started at. She says the kids are more laid back and very friendly. It has a hipster attitude but she said the professors and students seem to be more intellectually curious. She said kids are not there just to get all “A” 's but to actually learn and challenge each other. She said they go deeper in thought there and that fits her very well.
