Mid Century Vase - USA studio pottery

Hello-
I found this amazing mid century vase at an estate sale alongside some other stellar pottery.
The estate was of a woman who was a ceramics masters student at Denver University in the late 50's and early 60's. Alongside this amazing vase I also picked up; a Bernard Leach 'fish' bowl, a Janet Leach vase, 2 yunomis; 1 by William Marshall, 1 by Kenneth Quick, 2 other pieces I will also be asking for help with, and several other nice pieces. There were other pieces that I did not get by David Leach, more Bernard Leach pieces, several other Leach St Ives and other Cornwall potteries items, and a Jean Derval pitcher....among others.
This vase was among strong company to say the least.

I am still kind of dizzy from the experience...

It stands about 21 inches (53 cm) tall.

Please see attached and let me know what you think!
Thanks in advance for any info.

Here are 2 more shots of the mark- sometimes the angles reveal more...

The style of pot and decoration doesn't look British (or Continental) to me, and I don't recognise the mark, so I'm reasonably sure it's by a US studio potter. Best to try the themarksproject.org website which lists many American studio pottery marks.

Thanks Naomi- I have exhaustively searched The Marks Project ...to no avail. My inclination that it is not British either...due to style more than anything. I am sure I have seen something of similar style in past searches (looking for other pots/ marks), but this time I am not turning up anything remotely close... I will probably figure it out down the road when I am looking for something else!

This pot looks strangely unfinished.

Does anyone else think it could it be Betty Blandino? (couldn't stop researching...)

When I saw the mark I thought it looked similar to her mark................................. but she didn't throw and this vase looks thrown. Her pots were coiled and thin walled and, although they varied, I have not seen anything by her remotely like this.

Thanks-
I had kinda deduced the same from looking through her work online, but I had to throw it out there. This is definitely thrown, and 100% not 'thin' in any aspect; it's very well thrown, just more of a 'crock' thickness and heft. 'Substantial' I would call it.
I think the 'house' shape of the indentation is what differs it from any of her marks I have seen (not to mention overall style, method, ect)
The search continues...
