From Laub's Journal in a discourse from Joseph
"Now I will tell the designs of building the tower of Bable. It was
designed to goe to the city of Enoch, for the veil was not yet so thick that it
hid it from their Sight. So they concluded to goe to the City of Enoch, for
God gave him place above this impure Earth. For he could breath a pure
hair & him and his City was taken, for God provided a better place for him
for they was pure in heart. For it is the pure in heart that causes Zion to be
& the time will come again to meet, that Enoch and his city will come again
to meet our city & his people, our people, & the Air will be pure & the Lord
will be in our midst for Ever."
There are a lot of references and purported sayings from Joseph that the city was taken up from this earth and for a time remained visible to the inhabitants of the earth. Hence the tower of Babel
