A lost locality that was collected by Henry How (howlite) in the mid/late 1800s. On the Clifton Estate, site of the Haliburton House. The site was a gypsum quarry with some borates and other evaporite minerals.

How referred to the minerals as:
natro-boro-calcite (ulexite)
glauber salt (mirabilite)
cryptomorphite (ginorite)

This was the first Canadian occurrence for each of these minerals. It was the second known occurrence worldwide of ulexite.

The quarry occupied both sides of what is now Clifton Ave. The east side was filled in in the mid 1900s and is now built over. The west side is now flooded and is a lake.
