****UPDATE****Back in May, I posted a couple of photos taken by Stev Pitchford of Hostel #1 on Grass Mountain. New people being assigned to USTDC and elsewhere were often quartered there until they made other living arrangements.
George just sent me this great additional info on the old Hostel #1:
The Grass Mountain Hostel #1 is now Taipei Teachers' In-Service Education Center.
I searched the web in English but found very few info. The two best blogs in Chinese I found are the following:
The blog mentions the facility was used as dormitories by US military personnels until 1969.
The facility then was used by park authority until 1981 when the it became Taipei Teachers' In-service Education Center.
More photos including International Hotel and Chiang Ka- Sheik's summer villa.
****END OF UPDATE****
Using Google Earth, Stev has located the building as it exists today. Here are those images with his comments:
I found the Grass Mountain Hostel #1 building on Google Earth and here it is. I don't know what it's called now and the area has changed a lot over the years. You can see the old in the upper left quadrant of the first picture. Below that is the old basketball court where the Chinese kids used to run us ragged. To the right of the basketball court and just above the parking lot (which wasn't there in my time) is the hostel. The buildings immediately to the left, right, and above the hostel are all new to me. In the lower left quadrant of the picture you can see the pond that is in some of the Grass Mountain Park pictures I sent earlier.
Here is the old building. The driveway from the parking lot goes through the entrance canopy. You can see the second floor balcony sticking out under the roof on the right front side of the building. The roof with the lopped off corners on the left side of the building covers the sulfur pools. The front pool was open to the public and the back pool was for our use. I think the backs of the right wing and middle wing (not the wing containing the sulfur pools) have been cut off. If my memory is right, those wings extended back further and enclosed a little back yard.
The rectangular blue pool at the upper left is the old spring fed swimming pool. The faded green asphalt below the pool is the old basketball court.
