It would have been enough to almost make a huge temple.
This generation knew hoe to build things, to cut stone and to certainly to erect columns. I'm not saying that they actually did so here at this site, but I am saying it is possible. While many problems exist regarding Jabal al Lawz being the correct site og Mt. Sinai, it is far better than any of the other candidates out there, including the traditional site which has absolutely no archaeological evidence that the Israelites passed that way and stayed for almost a year.
