The artifacts you are seeing are likely voids in the SRTM data, which are due to the way the data was collected.

Googling for "void filling SRTM" will give you a lot of hits.

To get around the issue you either need to fill the voids yourself, or use a dataset were that has already been done. For example: http://opendem.info/download_contours.html There are however a number of different providers that you can choose from.
